Question

The most stable carbonium ion among these is:

• A. $C _{6} H _{5}- CH _{2} \overset{+}{C}H _{2}$
• B. $CH _{3} \overset{+}{C}H _{2}$
• C. $\left( C _{6} H _{5}\right)_{3}- \overset{+}{C}$
• D. $C _{6} H _{5} \overset{+}{ C } H _{2}$

Answer 1

The Correct Option is C

Due to more possibility for delocalisation of $\left( C _{6} H _{5}\right)_{2}- \overset {+}C - C _{6} H _{5}$ because of presence of $\pi-$ electrons in conjugation, $\left( C _{6} H _{5}\right)_{2}-\overset {+}{ C }- C _{6} H _{5}$ is the most stable ion.
