Question

Which of the following statements is not correct ?

A. Carbocation posses sextet of electrons.
B. The order of carbocation stability is :
$$\mathop C\limits^ + {H_3} > {\left( {C{H_3}} \right)_2}\mathop C\limits^ + H > {\left( {C{H_3}} \right)_3}\mathop C\limits^ + $$  
C. Carbocations have trigonal planar shape
D. Carbocations are formed by heterolytic cleavage
Answer :   The order of carbocation stability is :
$$\mathop C\limits^ + {H_3} > {\left( {C{H_3}} \right)_2}\mathop C\limits^ + H > {\left( {C{H_3}} \right)_3}\mathop C\limits^ + $$
Solution :
The order of stability of carbocations is :
$${\left( {C{H_3}} \right)_3}\mathop C\limits^ + > {\left( {C{H_3}} \right)_2}\mathop C\limits^ + H > \mathop C\limits^ + {H_3}$$
