The rate of solvolysis in ethanol is least for which of these compounds? A)C₆H₅CH₂Cl C)(C₆H₅)₂CHCl E)(C₆H₅)₃CCl

Question

Quizplus · Accepted Answer

The rate of solvolysis in ethanol is affected by the stability of the carbocation intermediate formed during the reaction. The more stable the carbocation, the slower the solvolysis rate because the intermediate can be stabilized by the solvent. In compound A, the carbocation formed would be stabilized by the adjacent sulfur atom, making it more stable and therefore less reactive in solvolysis. In contrast, compounds C and E contain a positively charged nitrogen atom, which is a strong electron-withdrawing group that destabilizes the carbocation intermediate, making them more reactive in ethanol solvolysis. Compound B is not a valid option as it is not a recognizable chemical structure.
