Q. Among the following carbocations : $Ph_{2} C^{+}CH_{2} Me \left(I\right), ph CH_{2} CH_{2} CH^{+} Ph \left(II\right), Ph_{2} CHCH^{+}M \left(III\right)$and $Ph_{2} C \left(Me\right)CH^{+}_{2} \left(IV\right),$ the order of stability is

WBJEEWBJEE 2012Organic Chemistry – Some Basic Principles and Techniques

Solution:

The order of stability of carbocation is $3^{\circ}$ benzylic $>2^{\circ}$ benzylic $>2^{\circ}>1^{\circ}$. Thus, the correct order of stability will be
