The correct stability order of carbocations is

1. CH 3 > CH 3 – CH 2 > CH 3 – CH > (CH 3 ) 3 C CH 3 + + + +
2. (CH 3 ) 3 C + > CH 3 – 2 H C + > (CH 3 ) 2 H C + > 3 H C +
3. 3 H C + > (CH 3 ) 2 H C + > CH 3 – 2 H C + > (CH 3 ) 3 + C
4. (CH 3 ) 3 + C > (CH 3 ) 2 H C + > CH 3 – 2 H C + > 3 H C +

Correct answer: (CH 3 ) 3 + C > (CH 3 ) 2 H C + > CH 3 – 2 H C + > 3 H C +
