Question

Clemmensen reduction converts a ketone to:
  1. A
    Alkane (−C=O → −CH₂−)
    Correct
  2. B
    Alcohol
  3. C
    Alkene
  4. D
    Carboxylic acid

Correct answer

Alkane (−C=O → −CH₂−)

Explanation

Clemmensen reduction: Zn(Hg) amalgam + conc. HCl converts C=O to CH₂. Used in acidic conditions (compare Wolff-Kishner: NH₂NH₂/KOH in basic conditions, same result). Used when base-sensitive groups are absent.
