Reduction of aldehydes & ketones by Zn-Hg amalgam and concentrated HCl results in conversion to an alkane. This reaction is known as:

Correct answer: D. Clemmensen reduction

  • A. Down Reduction
  • B. Cope Reduction
  • C. Wolff-Kishner Reduction
  • D. Clemmensen reduction
  • E. Sodium tetrahydroboride

Explanation

Clemmensen reduction is a chemical reaction used to convert carbonyl compounds (such as aldehydes and ketones) into alkanes. This reduction is typically carried out using zinc amalgam (Zn/Hg) in the presence of hydrochloric acid (HCl).
