Which of the following carbocations will be most stable ?
Updated On: Jun 18, 2022
- $Ph_{3} C^{ +}$
- $CH_{3}-\overset {+}CH_{2}$
- $\left(CH_{3}\right)_{2} \overset{+} CH$
- $CH_{2} =CH-\overset{+} CH_{2}$

The Correct Option is A
Solution and Explanation
The order of stability of given carbocations is
$\underset{\text{highly resonance stabilised}}{Ph_3C^+} > \underset{\text{resonance stabilised}}{CH_2 = CH - \overset{+}{C}H_2} >$
$ \underset{\text{stabilised by hyper conjugation}}{(CH_3)_2\overset{+}{C}H} > CH_3 \overset{+}{C}H_2$
$\underset{\text{highly resonance stabilised}}{Ph_3C^+} > \underset{\text{resonance stabilised}}{CH_2 = CH - \overset{+}{C}H_2} >$
$ \underset{\text{stabilised by hyper conjugation}}{(CH_3)_2\overset{+}{C}H} > CH_3 \overset{+}{C}H_2$
