GOC

Correct option is (1)..pls explain

According to me as well as I have studied its answer must be (2) because benzene will stablise the free radical.But if (2) is not given then definitely (1) will be the answer.Its order can be given as 2>1>3>4.But i will say please check it once more.
I hope you got it well.

@sri
Among all , resonance is most contributing factor.
Here compound 1 and 2 can show resonance.You can't compare the stability among these two. Now.. consider the hyperconjugation effect.
In compound 1......... 1 alpha hydrogen
In compound 2......... 0 alpha hydrogenSo, definitely option (1) is correct.

@sarthakbasak but option 2 has more resonating structures. Why is it more stable than 1?

@harshalpatil No actually stability of allylic and benzylic free radical due to resonance is same.

@harshalpatil got your answer ?? Srinidhi had said it already... Since they have the stability same , think about hyperconjugation.
