Which of the following organic reactions involves the conversion of carbonyl compounds such as aldehydes and ketones into hydrocarbons by reduction with zinc amalgam and concentrated hydrochloric acid?

💡 Solution & Explanation

The Clemmensen reduction specifically converts aldehydes and ketones into corresponding alkanes using zinc amalgam and concentrated hydrochloric acid. The Cannizzaro reaction involves disproportionation of aldehydes lacking alpha-hydrogen atoms in the presence of concentrated alkali. Aldol condensation forms beta-hydroxy carbonyl compounds, and Friedel-Crafts alkylation introduces alkyl groups onto aromatic rings. Understanding these named organic reactions is essential for multistep synthesis in synthetic chemistry.
