A) \[C{{H}_{3}}--\underset{C{{H}_{3}}}{\overset{+}{\mathop{\underset{|}{\mathop{C}}\,}}}\,--H\]
B) \[C{{H}_{3}}--\underset{C{{H}_{3}}}{\overset{C{{H}_{3}}}{\mathop{\underset{|}{\mathop{\overset{|}{\mathop{{{C}^{\,+}}}}\,}}\,}}}\,\]
C) \[\overset{+}{\mathop{C{{H}_{3}}}}\,\]
D) \[C{{H}_{3}}\overset{+}{\mathop{C{{H}_{2}}}}\,\]
Correct Answer: B
Solution :
The most stable carbocation is r-alkyl carbocation because the order of stability of alkyl carbocation is t-alkyl > s-alkyl > p-alkyl >\[CH_{3}^{+}\] carbocation. This stability order is described with the help of hyper conjugation and inductive effect. On the basis of hyper conjugation, \[{{(C{{H}_{3}})}_{2}}\overset{+}{\mathop{CH}}\,\] shows six resonating structures due to presence of six \[\alpha \,C--H\] bonds,You need to login to perform this action.
