In Oppenauer's oxidation,

Options

  1. Asecondary alcohol is oxidised to carboxylic acid in acetone solvent using aluminium tertiary butoxide
  2. Bsecondary alcohol is oxidised to carboxylic acid without affecting the C = C or C C bond by aluminium tertiary
  3. Csecondary alcohol is oxidised to ketone without affecting C = C or C C bond by aluminium tertiary butoxide
  4. Dsecondary alcohol is oxidised to ketone by chromic acid - pyridine complex.

Correct answer

C. secondary alcohol is oxidised to ketone without affecting C = C or C C bond by aluminium tertiary butoxide

Step-by-step solution

In Oppenauer's oxidation, secondary alcohol is oxidised to corresponding ketone in the presence of aluminium tertiary butoxide. Other oxidisable groups are not affected.
