Hello, I’m a Hong Kong student. It is sincerely appreciated that your video no matter is organic chemistry or physics. These videos totally save my college life. There is no words to express how much thankful am I.

Good Day sir. Though I may not know you, all I can is that this your channel is the BEST OR NUMBER ONE CHANNEL when it comes to knowledge. I started watching your videos since 2017, One of the reasons I graduated from college is because of your videos and teaching which was very apt for understanding. I really want to say I'm a highly grateful man, you have touched so many lives you don't know. God bless you richly sir 😭😭. I'm highly super grateful. Please don't stop for others who like me you gave hope and motivation to try better in our academics via your video. You gave touched so many lives that you can never imagine.

For problem #4, can you clarify this. U said the peak was at 1700 however the peak was presented after 2000, roughly 2200. Is this a mistake. This confused me as I see you had the C=O in all the answers but the peak was not presented around 1600

Wouldn't problem 5 be A because 2 peaks on the amine mean it is a primary amine? and answer D is a secondary amine.
@anjalikushwaha81849 ай бұрын
Answer D is primary amine as nitrogen is directly attached to one single carbon and not 2. At first I also thought the same but then after looking at it carefully I realised it just looks so because of the ring it appears as if it's attached to 2 carbon but no just 1. It's been a year though!😂

Im confused because my IR chart says an OH bond is between 3200 and 3500. Not at 3000
@camiloacevedo751610 ай бұрын
In my IR chart, we are given three options for OH bonds. When OH is present in an alcohol, phenols (dilute solutions), it is between 3590 and 3650. When OH is present in alcohol, phenols (hydrogen bonded) it is between 3200 and 3550. When OH is present in carboxylic acids (hydrogen bonded), it is between 2500 and 3000.
