Abstract
The discussion on the stability of different carbocations is one of the key topics in the teaching of organic chemistry at university.However, the results in one text or document often disagreed with those of the others.In this paper, we present the reasonable comparison and explanation about the different kinds of carbocations based on the comprehensive analysis of references, data and theory.
Keywords:Carbocations ;Stability ;Hybridization ;Electronic effect
