Question: Which of the following is most stable carbocation ?...

Which of the following is most stable carbocation ?

A

CH3C⊕H2\mathrm { CH } _ { 3 } \stackrel { \oplus } { \mathrm { C } } \mathrm { H } _ { 2 }

B

CH3C⊕=O\mathrm { CH } _ { 3 } \stackrel { \oplus } { \mathrm { C } } = \mathrm { O }

C

CH3−C⊕=NH\mathrm { CH } _ { 3 } - \stackrel { \oplus } { \mathrm { C } } = \mathrm { NH }

D

CH2=C⊕H\mathrm { CH } _ { 2 } = \stackrel { \oplus } { \mathrm { C } } \mathrm { H }

Answer

CH3−C⊕=NH\mathrm { CH } _ { 3 } - \stackrel { \oplus } { \mathrm { C } } = \mathrm { NH }

Explanation

Solution

Electron releasing [+M] effect of nitrogen stabilise the carbocation.
