An organic compound A reacts with sodium to evolve hydrogen and with oxidizing agents to yield a ketone. The formula of A would be:

A)  \[C{{H}_{3}}C{{H}_{2}}OH\]

B)  \[C{{H}_{3}}CHOH\cdot C{{H}_{3}}\]

C)  \[{{(C{{H}_{3}})}_{3}}C\cdot CHO\]

D)  \[HO-C{{H}_{2}}\cdot C{{H}_{2}}-OH\]

Correct Answer: B

Solution :

Alcohols shows weak acidic character, when treated with active metals like K or Na and evolve hydrogen. On oxidation, secondary alcohol yield ketone. Hence, the compound must be \[C{{H}_{3}}CHOH\cdot C{{H}_{3}}.\]
