  1. Question 1

    Q1. A chemist needs to reduce a ketone to an alkane using Clemmensen reduction. Which reagent combination is specifically required for this process?

    • A) Zn-Hg / conc. HCl
    • B) NH2NH2 / KOH
    • C) LiAlH4 / Ether
    • D) H2 / Ni

    Answer: Zn-Hg / conc. HCl

    Explanation: Clemmensen reduction uses Zn-Hg/HCl to reduce carbonyls to alkanes. It is unsuitable for acid-sensitive compounds, where Wolff-Kishner (basic) is preferred.
