Which of the following will be the major product when 3-phenylpropene reacts with HBr?

Options:

Answer:

Solution:

$C_{6} H_{5} - C H_{2} - C H = C H_{2} \overset{H B r}{\to} C_{6} H_{5} - C H_{2} \overset{+}{C H} - C H_{3}$

$\overset{1, 2- H^{\oplus} s h i f t}{\to} \underset{more stable carbocation}{C_{6} H_{5} - \overset{\oplus}{C H} - C H_{2} - C H_{3}}$

$\overset{{Br}^{Θ}}{\to} C_{6} H_{5} - \overset{Br}{\overset{|}{CH}} - {CH}_{2} - {CH}_{3}$
