Organic Chemistry on Khan Academy: Carbon can form covalent bonds with itself and other elements to create a mind-boggling array of structures. In organic chemistry, we will learn about the reactions chemists use to synthesize crazy carbon based structures, as well as the analytical methods to characterize them. We will also think about how those reactions are occurring on a molecular level with reaction mechanisms. Simply put, organic chemistry is like building with molecular Legos. Let's make some beautiful organic molecules!
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

This stuff made no sense to me when my professor taught it, the book confused me even more - thank you so much for making this super simple. NOW I understand what the professor and the book were trying to say. Both seemed to skip over these fundamental basics. I believe you just saved my next chemistry exam score lol

@nishantprakash5928 2 года назад

Your teacher skipped Nomenclature? Bruh get him fired

@brco2003 14 лет назад

Wow, I haven't seen chemistry in 4 years (and I'm also not so smart), but Sal's amazing teaching style made this so easy for me to understand.

organic chemistry suxa-dec

@nemegto 4 года назад

2:10 The prefix of 11 would be Undec not from french where un means one smh, it comes from latin undecim, meaning eleven :) Now that I think about it, most things in chemistry are prefixed in Greek; mono, di, etc. ANYWAYS just here to say that undecim comes from latin ._."

@farhanrkn 6 лет назад

I try to remember the 11 as Un decima. Real madrid got Un decima UCLs in 2016

@PANORC 10 лет назад

actually the prefixes from pent- , hex- etc ,come from the greek words for numbers,5=pente,6=hexi,7=hepta etc :). Great vid btw. thanks:))

@daggalegacy4441 7 лет назад

This video's been on youtube for 7 years and has less than a million views. Someone posts a lets play video and gets 5 million views in a week. Sad. I watched this series 5 years ago and it gave me enough knowledge where I'm no longer confused about organic chemistry and I can understand molecule diagrams on wikipedia. Invaluable.

@sidassassin6670 7 лет назад

true

@sidassassin6670 7 лет назад

people watch lets play video coz they cant play them

@Thingsyouhavetoknow 3 года назад

@mtflyer05 10 лет назад

You're lucky. Even if you grasp things when taught by your teacher, a new perspective is always helpful, too.

No 3 sigma bonded Carbons = C-C-C Prop= 3 carbons and to fulfill the octet rule you bond the carbons to the hydrogens

@kwonny1041 12 лет назад

U should be my chem teacher ;( I can totally understand them now! My teacher is really not good at teaching ... i don't understand what she's talking about Thank u!!

@NoRefundsXD 11 лет назад

I don't have to learn organic chemistry until next year. I'm going to be so far ahead of my class, it IS going to be funny. :) Thanks Sal!

@MsPotatobag 11 лет назад

My chemistry teacher has no idea what she's ever talking about, aha. things appear so much more straightforward when explained by you rather than her

@hunger4jsutice 11 лет назад

Excellent, clear teaching. You are my favorite Khan Academy teacher, whomever you are. You have helped me a lot in understanding the chemistry in physiology and now you are helping in my Organic Chem class. Thank You.

@XHUMBITO1 13 лет назад

the videos are great, and thank you very much. But, whats up with the voice volume? Its knida low, or maybe the problem is with my headphones. Thanx again ;).

@DietChoke4077 3 года назад

Anyone else up at 5:38AM binging these videos

@superdau 14 лет назад

As a note (I assume it will be covered in a later video anyway): the "octane" from the gas station is actually 2,2,4-Trimethylpentan, an isomer of octane. It has the same number of carbon and hydrogen atoms as the real octane, also no double bonds or cycles. But instead of a linear chain it has branches.

@jamesadams3373 4 месяца назад

If course is free, why are 34 videos hidden? Also, what year were these vids created? Thank you.

@ezman212 12 лет назад

Thanks a lot. Dude! O Chem looks easier now because of you. I finally understand and like Chemistry! Thanks you.

The methyl group is responsible for the potentiation of effects as compared to the related compound amphetamine, rendering the substance more lipid-soluble, enhancing transport across the blood-brain barrier, and more stable against enzymatic degradation by monoamine oxidase (MAO).

@denniskiplagat7525 10 лет назад

how come the cyclopentane has ten hydrogens and its an alkane? i think its supposed to be an alkene

@hayleecossette5200 7 лет назад

dennis kiplagat it's an Alkane because there is no double bonds

Egad, I need more hours in the day! I just came across Biomimicry. Last week all I could think about was Energy. Oh yeah an something called Rsa which is a drawing that explains something so you understand it. Whew! Maybe i need to try Decaf? Is it true? Did the IRS layoff its workers?
