TestHub · Accepted Answer

Concept: Sɴ1 versus Sɴ2 in benzylic systems, radical stability, and the effect of substituents.

Solution:

(A) is true; high temperature favors radicals.

(B) is false; the hydrolysis step involves a nucleophilic substitution mechanism.

(C) is false; electron-withdrawing groups (EWGs) destabilize the radical/transition state.

(D) is false; PCl₅ is used for $O H \to Cl$ or $C = O \to CC l_{2}$ conversions.

Final Answer: Option (A)
