In the reaction given below what will be the major product at the end :

Options:

Answer:

Solution:

The first step is anti addition of ${B r}_{2}$ across the double bond.

In the second step, $E t O^{-}$ $(n u^{-}$ ) gets added by $S_{N} 1$ mechanism. And $B r^{-}$ from the dashed position acts as the leaving group leads to the formation of a stable benzylic carbocation.
