Dude. Thanks. My organic chem lecturer is useless. I streamed this video for over 400 students and the class average went from 30% to 67%. Thanks man. How can we contact you?
@@filistineHuraa honestly ap chem was harder for me, but that's because all the info was new. Now that I'm basically taking it again in college, I know alot of the stuff so it's actually really easy.
hiii, I was wondering if you can tell me if I can study all the ap chem lessons from him? My teacher is useless and I don't understand a word from her 😭 Are his videos really enough to get a 4-5 in the AP?
I don't know how many exams you have gotten me through at this point, but you're an absolute hero. They day I get my degree, it will seriously be partially thanks to you. The amount of things that I have gone from being "yeah okey, but I don't get it" to "Oh. But why didn't they just say so" thanks to your work is at this point more than I can count. You are genuinely a beautiful unicorn.
I just want to say that I have been absolutely dreading my upcoming exam until I found your channel I feel I will be much better off watching your videos! I have been binge watching I will comment my grade after my exam!
I should be paying my tuition to you because my teacher speeds past everything! I’ll post my exam score on this Chapter after I get it back. edit: So I checked my Exam Score and got a 106! I can't express how thankful I am to you sir, you make hard things easy to understand.
Hello Sir, I am from South Africa I am doing my First year at the University of Pretoria. I really really liked no I love your way of Tutoring. You are the best May God bless you. Thank you very much I hope you get the support you need so you can continue your work.
I absolutely plan on joining your membership program as soon as I have extra funds. Youre videos have completely changed learning for me and every time I have struggled with a concept in class this is the first place I come to and my ability to comprehend the subject matter expands exponentially every time. thanks to your channel I have successfuly gotten through all my classes with As and Im so thankful! Just wanted to thank you for everything you do!
I cried out of joy during your video because I was so frustrated and confused with this concept but when you explained it, I understood every single bit. Thank you! You’ve made me fall in love with chemistry
This review is so awesome! For the first time ever this stuff makes so much sense to me than it did when I was in school learning this! I wish I had this type of instruction back in school, maybe I wouldn't have struggled so much! Thanks for simplifying this:)!
So very happy to have found this video. I am amazed at what I was able to understand within the hour that I could not get from my terrible textbook that I have read over and over again. Online classes are much easier with your videos. Thank you!
thank you sooo much for this video, i have been struggeling for 2 days to make sence of the formulas for like L^2=l(l+1)h^2 etc. for an upcoming quantum mechanics exam... this video helped me more than 2 days of deciphering a physics textbook. you are literally a legend
I love chemistry, I am in uni, my major is chemistry, I pass exams, usually due to hard work, but when I open (1000+ pages) organic chemistry text book or even worse( 700+ pages) of inorganic chemistry text book, not even going to mention analytical chemistry I sometimes want to cry, but after I watch your videos I am amazed how large is the power of a good presenter, calm voice and extraordinary explanation, don't get me wrong I love my professors, they are awesome and assistants during labs are really kind, I am enjoying the beauty of chemistry, but the fact that u tried a lot to make so many high quality videos, and the fact I can pause to try the example for my self, to go back if I missed something (...) thank you RU-vid and thank you Organic Chemistry Tutor, I am at year two, next year, (hopefully I will get there) I will write dedication to your channel in my bachelor thesis, I came back to this video because I could not remember the name of Aufbau principle, but I knew how to apply it and that u wrote the name in the description. Thank you!
Thank you so much for your videos, I prefer 1 hour with you than a week in the classroom. I’m passing all my tests with good grades thanks to your great explanations.
4s is higher in energy level (this is what I thought) but since it's for the stability of an atom, 4s will be filled first, that is if 3d is already half filled or completely filled. (again, I'm not pretty sure about this, correct me if I'm wrong)
Tutor: Now if the last vacant room is in the second floor, would you mind climbing up one flight of stairs to go to the second floor to get that room? To have your own space and be comfortable? Me: I wont mind...unless you're who I'm gonna share the room with OwO
Is 4s level higher or lower than 3d level? Because before you said that electrons from higher energy levels should be removed and you removed 4s2, but then you put 3d at higher level than 4s in the arrows part I am confused.
Superb job of explaining some very fundamental information. This video sums up in 90 minutes what many lower-level chemistry professors struggle to impart in several hours of lecture. Very nicely done.
Got a 90 on my gas law exam thanks to you, unfortunately I didn’t find you earlier so I got a 48 on my previous exam. I’m gonna try and come back this semester with your help but I think the 48 may be too low. Thank you for all your help.
You're very welcome. Great job on getting a 90 on your Gas Laws exam. Here is my general chemistry playlist if you need to help with future topics for your next exam: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-bka20Q9TN6M.html
you're literally the only reason why im passing chemistry. I haven't even looked at my book, but one of you videos is worth an entire lecture and more understanding. Keep doing what you do
Really helpful, especially the explanation I needed at around the 51:00-52:00 timestamp with regard to relating the quantum numbers to electron configuration diagrams. Thank you so much!
at 32:05 4s(4+0) is of less energy than 3d(3+2). Electrons will prefer to leave and enter low energy orbital first. Yeah, this is kinda hard to digest. But this is what happening here. THANKS FOR UR WONDERFUL LECTURES . RESPECT :)
what is the possible 4 quantum numbers for the last e- in the fluorine ??? this question in my book ... the answer is ( n=2 , l=1 , ml= -1 &0 &1 , ms=-1/2 &+1/2 ); ( &=or ) .... that's false right ??
Hello, Just want to say I really appreciate the time and detail you have put into this video, it is so helpful. I hope you exceed in your life goals whatever they may be and I feel you deserve so much for selflessly helping all of us who are lost in Chemistry land. ;P Cheers!
at around 31 minutes. For Fe+2 you say to remove the electron from the higher energy level 4s rather than 3d. Later, while explaining the exception for Cr, you say that 3d is a higher energy level than 4s. So that contradicts what you said earlier. I do believe 3d is a higher energy level, so I'm confused as to why you would remove the two electrons on the 4s level.
Actually he is WRONG. The correct configuration would be 4s1, 3d5, you can't have 2 electrons sharing an orbital in 3d while there is an empty orbital in 4s
Thank you so much!!🥺🙏Gosh, imagine how many students you've helped and will help because of your videos. And those students will grow up to become professionals someday. You are literally a blessing to the society🙏🤍
KEPT ME FROM SUICIDE😂😂😂😂🙏🏽🙏🏽🙏🏽✨💯💯💯💫🌸LOL . THANK YOU AND GOD MAY BLESS YOU FOR MANY YEARS TO COME BRO. SERIOUSLY I HOPE YOU MAKE IT FARTHER THAN YOU HAVE EVER IMAGINED. I AM REALLY PRAYING YOUR WILDEST DREAMS COME TRUE🌸💯🙏🏽💦💦 YOU ARE A 💎 💯✨✅⭐️💫💫💫💫💫💫💫💫💫💫
I dont get why the Fluorine 2p + 3s = 2p^5 BUT THE Phosphorus's 2p + 3s = 2p^6.... I DONT GET IT. PLEASE SOMEONE EXPLAIN...HOW THE SAME THING TURNED INTO 2p^6 when it was 2p^5 in the first one.... (The first 2 Elements around 0:00 - 6:16 )
You are a life saver during this quarantine learning inorganic chem for my bachelor without interaction with the lecturer is hard but ur videos are the best👍👍👍💪💪💪💪
Mire ha mi yo tengo halgo ke exponer sobre Hoyente ha distansia local pertenese X X X y los primos son grupo de paso DESPUES no ANTES de GANAR (cual esDECAENSIA o DOCTOR) como dise sienpre gana ooo lo de Doctor
I have a question for the chromium part, is chromium the only exception? I searched the electron configuration of vanadium with atomic number 23, why does the electron in the 4s sublevel does not jump to the 3d sublevel? Instead, it remains in the 4s sublevel existing as a paired electron and has a electron configuration of [Ar] 3d³ 4s². Why?
Julio, in min 33.17 you said that chromium has 28 protons. What do I not have clear? My understanding is that protons call the element it is. With 28 protons would not it be Nickel? Or if someone can chip in to get me out of the woods? Pleaseee?
Good...but isn't the electron configuration for Fe+2 gonna be 4s1 3d5, because just for the atom to be stable, the valence sub shell must contain of orbitals of fully paired electrons or all of them unpaired unless the atom is in exited state, ....can u plz elaborate a bit about it
Hey Organic Chemistry Tutor, thank you so much for these very, very helpful videos! You take these concepts from all these subjects and you simplify it with such ease. I appreciate that a lot. I was wondering if you could help answer a question I have at around 57:45, regarding ms. I initially thought that it would be +1/2, but then when I un-paused the video, I see that ms can equal both +1/2 and -1/2. I was thinking, how come it can be -1/2, too, if when we draw the arrows in, they must be in the up configuration first, and then the down configuration? Thanks so much in advance!!
I think 85% of my fees should be paid to you, all that those guys know better is to give tests and quizzes. one last request sir, can I see your face please. please
