  1. Question 1

    Q1. During the reaction of Hydrogen Cyanide with Ethanone, what is the initial and most critical step in the reaction mechanism according to PTB?

    • A) Nucleophilic attack on Carbon
    • B) Electrophilic attack on Carbon
    • C) Nucleophilic attack on Oxygen
    • D) Free radical substitution

    Answer: Nucleophilic attack on Carbon

    Explanation: Nucleophilic addition involves the nucleophile attacking the electrophilic carbon. Oxygen acts as a Lewis base by accepting a proton, not as the primary electrophile.
