Which one of the following undergoes reaction with 50 % sodium hydroxide solution to give the corresponding alcohol and acid?

Options

  1. APhenol
  2. BBenzaldehyde
  3. CButanal
  4. DBenzoic acid

Correct answer

B. Benzaldehyde

Step-by-step solution

A+ NaOH alcohol + acid Thus, it is Cannizaro reaction. A is thus aldehyde without H at -carbon. (like . C ₆ H ₅ CHO , HCHO )2 C ₆ H ₅ CHO (benzalhyde) + NaOH C ₆ H ₅ CH ₂ OH + C ₆ H ₅ COONa
