Question

Acetonitrile on acidic hydrolysis gives –
A) $HCOOH$
B) $C{H_3}NC$
C) $C{H_3}COONa$
D) $C{H_3}COOH$

Answer 1

Any chemical reaction in which a water molecule breaks one or more chemical bonds is known as hydrolysis. The term refers to any substitution, reduction, or solvation reaction in which the nucleophile is water. Condensation reactions, in which two molecules combine to form a larger one and eject a water molecule, can be reversed by hydrolysis reactions.

Complete answer: Acid hydrolysis is a hydrolysis reaction in organic chemistry in which a protic acid is used to catalyse the cleavage of a chemical bond with a nucleophilic substitution reaction with the addition of water. In the conversion of cellulose or starch to glucose, for example. It can be characterised as an acid catalysed nucleophilic acyl substitution reaction in the case of esters and amides.
The chemical compound acetonitrile, also known as methyl cyanide, has the formula $C{H_3}CN$. The most basic organic nitrile is this colourless liquid (hydrogen cyanide is a simpler nitrile, but the cyanide anion is not classed as organic). It is primarily developed as a by-product of the acrylonitrile manufacturing process. It's used in organic synthesis and butadiene purification as a polar aprotic solvent.
The nitrogen atom in acetonitrile has a free electron pair, allowing it to form a variety of transition metal nitrile complexes. It is a ligand that is easily displaceable due to its poor basicity.
Acetonitrile on hydrolysis produces ethanoic acid or it can also be represented as $C{H_3}COOH$.
The correct option is D.

Note:
Acetic acid is used in many manufacturing processes to make substrates and as a chemical reagent to make a variety of chemical compounds such as acetic anhydride, ester, vinyl acetate monomer, vinegar, and a variety of other polymeric products. It can also be used as a solvent for recrystallization, which makes it useful for purifying organic compounds.
