Arrange the following carbocations in order of decreasing stability:

Question

Quizplus · Accepted Answer

The stability of a carbocation depends on the number of alkyl groups attached to the positively charged carbon. The more alkyl groups there are, the more stable the carbocation. In option A, carbocation A has only one methyl group attached to the positively charged carbon, which makes it the least stable. Carbocation C has three methyl groups, making it the most stable. Carbocation B has two methyl groups and is intermediate in stability between A and C. In option B, the order is reversed, which is incorrect. Option C has the same order as option A, which is also incorrect. Option D has the correct order, with carbocation C being the most stable, followed by A and then B. Option E is incorrect as it puts B as the most stable carbocation which is not true.
