An organic compound `A` is a constituent of antifreeze and has the molecular formula `C_(2)H_(6)O`. Upon reaction with alkaline `KMnO_(4)`, the compound `A` is oxidised to another compound `B` with formula `C_(2)H_(6)O_(2)`. Identify the compounds `A` and `B`.

Options

A. benzene, butanone
B. Ethanol, Ethanoic acid
C. ethanoic acid, pentanone
D. butanal, methane

Answer

B

Explanation

The compound 'A' is ehanol and with alkaline `KMnO_(4)`, it is oxidised to ethanoic acid 'B'. The chemical equation for the reaction is :
`underset("Ethanol (A)")(C_(2)H_(5)OH)underset(KMnO_(4))overset("Alkaline")tounderset("Ethanoic acid (B)")(CH_(3)COOH)`
