Q. Consider the following carbocations, stability of carbocations increasing order
(I) $(C)_{6}( H )_{5} \overset{+}{ C }( H )_{2}$
(II) $(C)_{6}( H )_{5}( CH )_{2} \overset{+}{C} ( H )_{2}$
(III) $(C)_{6}( H )_{5} \overset{+}{ C }( HCH )_{3}$
(IV) $(C)_{6}( H )_{5} \overset{+}{ C }\left(( CH )_{3}\right)_{2}$

Solution:

Resonance and inductive effect decide stability of carbocations.

Solution

∴ Correct order of stability is

(II) < (I) < (III) < (IV)
