What is (are) the missing reagent(s) in the reaction below?

Question

Quizplus · Accepted Answer

The reaction is an alkylation reaction, and the missing reagent is a source of cyanide ion, which can act as a nucleophile to attack the alkyl halide. Option A (NH₃) is not a known reagent for this reaction. Option B (HCN) is a mild nucleophile and does not work well for alkylation reactions. Option D (NaNH₂) is a strong base and may cause elimination instead of alkylation. Option C (NaCN, NH₄Cl) is the best choice as it provides the necessary cyanide ion for the reaction while the NH₄Cl serves as a catalyst to improve the yield.
