Question

6 multiple choice 2 points rank the following carbocations in order of stability. (the most stable is first.) previous

Explanation:

Step1: Identify carbocation types

I is a secondary benzylic - like carbocation, II is a secondary carbocation, III is a primary carbocation.

Step2: Recall stability rules

Stability of carbocations: tertiary > secondary > primary, and benzylic > non - benzylic. Benzylic carbocations are stabilized by resonance.

Step3: Rank stability

Since I has resonance stabilization due to its benzylic - like nature and is secondary, II is just a secondary carbocation, and III is a primary carbocation, the order of stability is I > II > III.

Answer:

I > II > III
