Answer 1

Answer:

Firstly look for the stability of the possible compounds given in the options.

For Hoffman's product, we have 3 conditions according to my knowledge. They are as follows:

1. Leaving group is a poor leaving group like fluoride group.
2. When a sterically most hindered base is used.
3. There is a possibility of formation of a conjugation i.e., alternate double bonds....
