Among the given cation,s the most stable carbonium ions is ?

Options

A. Sec-butyl
B. Ter-butyl
C. n-butyl
D. None of these

Answer

B

Explanation

`CH_(3) - overset(CH_(3))overset(|) underset(CH_(3))underset(|)(C^(+)) gt CH_(3) - underset(CH_(3))underset(|)( C) H^(+) gt CH_(3) - C H_(2)^(+) gt underset("Methyl carbocation") (CH_(3)^(+))`
Greater the no. of alkyl groups, greater would be the dispersal of the charge and hence more stable will be the carbonium ion.
