Question

(A).$C{H}_{3}COOH$
(B) $C{H}_{3}COC{H}_3$
(C) $C{H}_{3}CO\stackrel{\oplus }{N}{H}_3\stackrel{(-)}{C}l$
(D) $C{H}_{3}N{H}_2$

Answer 1

Hint: Acetamide is an organic compound which releases nitrogen gas from the solution when reacted with $NaN{O}_2/HCl$.It is the simplest amide derived from acetic acid. It finds some use as a plasticizer and as an industrial solvent.

Complete step by step answer:
We know the given compound $$C{H}_{3}CON{H}_2$$ commonly known as acetamide is a organic compound with structure as: -

It is the simplest amide with IUPAC name ethanamide and is derived from acetic acid by the reaction with ammonia
$C{H}_{3}COOH(AceticAcid)+H-N{H}_2(Ammonia)\to C{H}_{3}CON{H}_2(Ethanamide)$
In industries, acetamide is produced by dehydrating ammonium acetate or via hydration of acetonitrile.
i.e. $C{H}_{3}CN+H_{2}O\to C{H}_{3}CON{H}_2$
Ethanamide is used as a plasticizer and an industrial solvent. It has uses in electro chemistry and organic synthesis of pharmaceuticals, pesticides and antioxidants for plastics. When $C{H}_{3}CON{H}_2$ is reacted with $NaN{o}_2$ in the presence of $HCl$, we get $C{H}_{3}COOH$(acetic acid) as the main product.

Note:
Acetic acid will also be formed from ethanamide if the reagent is $HN{O}_2$. Moreover, when ethanamide is treated with water, it also yields acetic acid.
i.e. $C{H}_{3}CoN{H}_2+H_{2}O\to C{H}_{3}COOH+H_{2}O$
