A compound 'A' having the molecular formula `C_5H_12O` on oxidation gives a compound B with molecular formula `C_5H_10O`. Compound B gave a 2,4 dinitrophenylhydrazine derivative but did not answer haloform test or silver mirror test. The structure of compound A is

Options

A. a) `CH_3-CH_2-CH_2-CH_2-CH_2-OH`
B. b) `CH_3-CH_2-underset(OH) underset|CH_2CH-CH_3`
C. c) `CH_3-CH_2-underset(OH) underset|CH-CH_2-CH_3`
D. d) `CH_3-CH_2-underset(CH_3) underset|CH-CH_2-OH`

Answer

C

Explanation

Since, the compound B gave a 2,4 dinitrophenylhydrazine derivative but did not answer halogen test or silver mirror test. It must contains `a gt C=0` group, but it is neither a methyl ketone nor an aldehyde.
Moreover compound B is obtained by the oxidation of compound A, having molecular formula `C_5H_12 O`, so the compound A must be a secondary alcohol.
