Question

Compound ‘A’ was prepared by oxidation of compound ‘B’ with alkaline KMnO₄. Compound ‘A’ on reduction with lithium aluminium hydride gets converted back to compound ‘B’. When compound ‘A’ is heated with compound B in the presence of H₂SO₄it produces fruity smell of compound C to which family the compounds ‘A’, ‘B’ and ‘C’ belong to?

✓

Answer

'A' is carboxylic acid (R-COOH), 'B' is an alcohol (R-CH₂OH) and 'C' is an ester (RCH₂-COOR)

$\text{R}-\text{CH}_2\text{OH}\xrightarrow{\text{Oxidation (KMn O}_4)}\text{R}-\text{COOH}\\\ \ \ \ \ \ \ \ \ ^\text{(B)}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ ^\text{(A)}$

$\text{Alcohol (B)}\xleftarrow{\text{LiAlH}_4,\text{reduction}}\text{Carboxylic acid (A)}$
