I currently have an A+ in organic chem thanks to you. Honestly, I know enjoy chem because of your videos. I used to sooooo hate chemistry. Thank you very much for your efforts and help.
Your amazing man, ever since I started watching your videos, you have inspired me to go on and pursue chemistry. Currently in my 2nd year and whenever someone complains about chem or organic I direct them to you! Thanks a ton!
I really don't think that I'll be able to pass AS chemistry if it wasn't for your videos!! Thank you so much!! Chemistry is like wayyyy more fun with youuu!
Good explanation. Thanks for your efforts. Also I have shared this video with a high school student who will be having a text very soon. New York City schools are having online classes because of the COVID-19 pandemic, but some of the instruction lacks needed details. This video has helped to fill some of the gaps. Thank you again.
I’m medical student from Iraq 🇮🇶 I’m really in love with your explanation your videos are so useful & interesting for me ☘️🌹 Thank you so much 🤍🙏🏻🌸 You’re really Talented 👍🏻🌸
YOU ARE JUST A LIFE SAVERRR, I'VE BEEN STRUGGLING WITH CHEMISTRY BUT I REALLY ENJOY WATCHING YOUR VIDEOS. THANK YOU SO MUCHHHHH!! (I have exam today and I'll be back after hehe)
how do you understand which one has more priority in which case? as in you mentioned ‘in this particular reaction’ so i am guessing it varies from formula to formula?
Still if you put 1 in the name, that should be 2-cyclopenten-1-one since no vowels should be following each other. You can also name it as cyclopent-2-en-1-one. But as always said, 1 is optional in cyclic chains unless there are more than one of that specific functional group, where you should always indicate their carbon numbers.
i know no one’s going to answer this until it’s of no use to me but i’m confused. the structure at 10:37 was said to have a alcohol (the OH at 3). i thought alcohol was only allowed at the end of the chain? or is that only carboxylic acid. even so, why was the name hydroxy?? isn’t it 3-methol? isn’t the IUPAC suffix for alcohol “ol”? where did hydroxy come from ??
Here is the arrangement of their priorities from highest to lowest: 1. Carboxylic acid 2. Esters 3. Amide 4. Aldehyde 5. Ketone 6. Amine 7. Alkyne 8. Alkene 9. Alkane
A carboxylic acid group is always COOH while alcohol is simply OH so if there's an alcohol attached, it is only C bonded to OH without the double bond to O on the same C
A carboxylic acid has a carbonyl group which is an oxygen atom that is double bonded to a carbon. Carboxylic acids can only be found at the ends of an organic compound which is different from alcohols since they can be present in any of the carbons in the longest chain of a compund.
iirc names like butan-2-ol follow the more modern naming convention whereas 2-butanol is the "old way" that is still used pretty often. Both are correct
I know this is really late but an amide is a carboxylic acid derivative, which means the hydroxy group (OH) in carboxylic acid is replaced by an amino group (N). Which is why this NH2 in the video is just an amine, not amide.
