Question
Which of the following analytical statements completely contradicts the fundamental thermodynamic and stereochemical principles of the $S_N1$ mechanism?
💡 Solution & Explanation
The $S_N1$ mechanism involves the separation of charge in the rate-determining step to form a carbocation and a halide ion. This ionization strictly requires highly polar protic solvents (like water or alcohols) that can effectively solvate and stabilize both the developing positive and negative charges. Non-polar aprotic solvents like benzene completely fail to stabilize these ions, massively increasing the activation energy and suppressing the $S_N1$ pathway.
