Question

An organic compound (A), $C_2H_5NO_2$ gives on reduction another compound (B) $C_2H_7N$. The reaction of nitrous acid on (B) evolves nitrogen and gives another compound (C) $C_2H_6O$. The compound (C) on oxidation gives acetic acid. The compounds A, B, C are

• A. Nitroethane, Ethylamine, Ethyl alcohol
• B. Nitroethane, Dimethylamine, Ethyl alcohol
• C. Nitroethane, Dimethylamine, Acetone
• D. None

Answer 1

Answer: (A)

Nitroethane, Ethylamine, Ethyl alcohol

Answer 2

{\underset{\mathrm{Nitroethane , (A)}}{ {CH_5H_5 - N \equiv C}}$->[reduction]$\underset{\mathrm{Ethylamine , (B)}}{ {CC_2H_5NH_2}}->[HNO_2][-N_2,H_2O]} {\underset{\mathrm{Ethyl , alcohol, (C)}}{ {C_2H_5OH \equiv C}}$->[{[O]}][-H_2O] CH_3CHO ->[{[O]}]$\underset{\mathrm{Acetic , acid}}{ {CH_3COOH}}}
