Which compound undergoes the fastest S_N1 solvolysis reaction with water in acetone?

Question

Quizplus · Accepted Answer

The rate of solvolysis in SN1 reactions is dependent on the stability of the carbocation intermediate formed. In this case, (CH3)3C+ is the most stable carbocation as it is tertiary, while (CH3)2CH+ and CH3CH2+ are secondary and primary carbocations respectively. Therefore, the fastest reaction will be the one with the most stable carbocation intermediate, which is compound C, (CH3)3CBr.
