Question

An alkyl halide is capable of undergoing both $S_N1$ and $E1$ mechanisms since both share the same initial rate-determining step. Which condition strongly shifts the reaction to favor the $E1$ elimination pathway?

Answer: C

💡 Solution & Explanation

High temperatures heavily favor elimination ($E1$) over substitution ($S_N1$) because elimination produces more product molecules (like an alkene + acid), leading to a favorable increase in system entropy ($\Delta S$).
