Question 1
Which reaction involves the conversion of aldehydes into alcohols?
  • Oxidation
  • Reduction✔️
  • Hydrolysis
  • None of these
Correct Answer Explanation
Aldehydes (\(RCHO\)) are converted to primary alcohols (\(RCH_2OH\)) by reduction — adding hydrogen across the \(C=O\) bond. Common reducing agents include \(\text{NaBH}_4\) (sodium borohydride) and \(\text{LiAlH}_4\) (lithium aluminium hydride). Oxidation of aldehydes gives carboxylic acids, not alcohols. Hydrolysis is for esters, amides, etc.
