पर्याय

• Carbocation posses sextet of electrons

• The order of carbocation stability is:

  \[\ce{\overset{+}{C}H3 > (CH3)2\overset{+}{C}H > (CH3)3\overset{+}{C}}\]

• Carbocations have trigonal planar shape

• Carbocations are formed by heterolytic cleavage

Answer 1

The order of carbocation stability is:

\[\ce{\overset{+}{C}H3 > (CH3)2\overset{+}{C}H > (CH3)3\overset{+}{C}}\]

Explanation:

The order of stability of carbocations is:

\[\ce{(CH3)3\overset{+}{C} > (CH3)2\overset{+}{C}H > \overset{+}{C}H3}\]

This order can be explained on the basis of hyper conjugation and Inductive effect.
