I found this question and the answer as shown in my book. I didn't understand why the bromine particularly entered the position shown in the answer.
First of all, if a free radical was generated there it would be 2°, and also will have resonance. Is any other product possible or this is the only major product?
Also, is this allylic bromination? Every allylic position is also a vinylic position — I am not getting it.
