Question

Which of the following statements is not correct ?

• A. Carbocation posses sextet of electrons.
• B. The order of carbocation stability is :
  $\overset{+}{C}H _3 >\left( CH _3\right)_2 \overset{+}{C}H >\left( CH _3\right)_3 \overset{+}{C}$
• C. Carbocations have trigonal planar shape
• D. Carbocations are formed by heterolytic cleavage

Answer 1

Answer: (B)

The order of stability of carbocations is :
$\left( CH _3\right)_3 \overset{+}{C} >\left( CH _3\right)_2 \overset{+}{C}H > \overset{+}{C}H _3$
This order can be explained on the basis of hyper conjugation and Inductive effect.
