  1. Question 1

    Q1. What is the primary role of a basic catalyst in the addition of hydrogen cyanide to a ketone?

    • A) Increases nucleophilic character of the reagent
    • B) Increases electrophilic character of carbon
    • C) Protonates the carbonyl oxygen
    • D) Decreases the steric hindrance

    Answer: Increases nucleophilic character of the reagent

    Explanation: In base-catalyzed addition, the base generates a strong nucleophile by removing a proton from the reagent. Acid catalysis increases the electrophilicity of carbon.
