Question

The products of the reaction will be
$C_{6}H_{6}+CH_{3}-CH_{2}-CH_{2}-Br\overset{A n h y . A l B r_{3}}{ \rightarrow }$

• A. $C_{6}H_{5}-CH_{2}-CH_{2}-CH_{3}$
• B.
• C. as major product and $C_{6}H_{5}-CH_{2}-CH_{2}-CH_{3}$ as minor product
• D. 1: 1 mixture of $C_{6}H_{5}-CH_{2}-CH_{2}-CH_{3}$ and

Answer 1

Answer: (C)

Here the major product is 2-phenylpropane and minor is 1-phenylpropane as follows

It involves rearrangement of carbocation as follows
$\underset{p ^\circ l e s s s t a b l e}{C H_{3} - C H_{2} - \overset{\oplus}{C} H_{2}}\overset{H^{-} s h i f t}{ \rightarrow }\underset{s ^\circ m o r e s t a b l e}{C H_{3} - \overset{\oplus}{C} H - C H_{3}}$
