Equilibrium

Question

Wired Faculty App

The most stable carbonium ion among the following is

$C_{6} H_{5} - {CH}_{2} \overset{+}{C} H_{2}$

${CH}_{3} \overset{+}{{CH}_{2}}$

$C_{6} H_{5} - \overset{+}{C} - C_{6} H_{5}$

$C_{6} H_{5} \overset{+}{C} H_{2}$

Solution

C.

$C_{6} H_{5} - \overset{+}{C} - C_{6} H_{5}$

Due to more possibility for delocalisation in

$C_{6} H_{5} - \overset{+}{C} - C_{6} H_{5} (of π - electrons), C_{6} H_{5}_\overset{+}{C} - C_{6} H_{5} is the most stable ion .$
