Thanks so much Sir and more Grace. You are the BEST!

4:18 - How would you know what product to expect? Clearly you know, but how, why?

[@inthujan1716]

During this reaction two types of products form the major and minor product. The major product would be the one in which the Hydrogen in HBr attaches itself to the rightmost carbon (Markovnikov's rule) and Br attaches to the second carbon from right. The minor product will be when the opposite happens Hydrogen attaches to the second carbon and bromine to the first carbon.

Small comment to 13:35 - as far as I remember, five membered rings are preferred over six membered ones in terms of stability.

[@owo2519]

No, 6 membered ring is preferred more than 7 membered one. 6 membered ring is much stabler than 5 and 7, because of less ring strain and has stable conformers

4:40 is that markovnikkoff's rule?

[@perryperry7257]

28:15 why does the oxygen in NO2 have a negitive charge
Some one please explain

[@architbhagat]

Oxygen and the members of Oxygen family tend to form 2 bonds with other atoms. However, they if form a single bond, they acquire a negative charge on them. And if they form 3 bonds, they acquire a positive charge. The Oxygen atom in this case has only one bond (With Nitrogen), so it has acquired a negative charge on it. Similarly, Nitrogen and it's family form 3 bonds but in this case, N has 4 bonds so it has a formal charge of +1.
If you want detailed explanation, you can search for other videos on this channel. It really helped me with my Organic chemistry.

what are other reaction mechanism

I'm not familiar with this can you teach me this concepts?

[@lokeranerup1212]

At 21:42 , why does the Br decide to just up and leave? I understand the rest of the reaction, but that start is kinda weird imo. I first thought that since Br is quite electronegative, then the carbon it is attached to would have a positive charge and that the methanol would attack that carbon, effectively forcing the Br out with the electron. Pls halp
