Which of the following reagents converts both acetaldehyde and acetone to alkanes ?

Options

  1. ANi / H ₂
  2. BLiAlH ₄
  3. CI ₂ / NaOH
  4. DZn - Hg / conc. HCl

Correct answer

D. Zn - Hg / conc. HCl

Step-by-step solution

Clemmensen's reduction (conc. HCl / Zn - Hg ) or Wolf-Kishner reduction ( C ₂ H ₅ ONa / NH ₂ NH ₂ ) can be used to convert C = O group into CH ₂ group.
