What is the correct order of stability of the following carbocations (more stable less stable)?

Question

What is the correct order of stability of the following carbocations (more stable > less stable)?

Quizplus · Accepted Answer

The stability of carbocations is based on the concept of electron delocalization, which is facilitated by neighboring alkyl groups. Therefore, in the given carbocations, the stability order is based on the number of alkyl groups bonded to the carbon with the positive charge. Carbo cation 2 has two alkyl groups bonded to the positively charged carbon, making it the most stable. Carbo cation 3 has only one alkyl group, making it less stable. Carbo cation 1 has no alkyl groups, making it the least stable. Hence, the correct order of stability is 2 > 3 > 1, which is given in choice C.
