Question

In Reaction $ C{H_3}OH + PC{l_3} \to A\xrightarrow{{KCN}}B\xrightarrow{{hydrolysis}}C $
Then "C" is:
(A) $ C{H_{3}}C{H_2}OH $
(B) $ C{H_3}CHO $
(C) $ C{H_3}COOH $
(D) $ C{H_2}OH - C{H_2}OH $

Answer 1

Hint: The reaction with phosphorus chloride gives alkyl halide and with KCN gives potassium cyanide. In hydrolysis, water molecules are usually bound to two parts of a molecule. The hydrogen ion is obtained by one molecule of a substance and the OH group is received by the other molecule. The reaction of hydrolysis is generally used to break down polymers into monomers.

Complete step by step answer
The act of separating chemicals by adding water literally implies hydrolysis. The water reaction with another chemical compound results in two or more products being formed. Dissolving a salt with a weak acid or base in water or dissolving sulphuric acid in water where hydronium and bisulfate compounds are formed are some examples of hydrolysis. Hydrolysis also helps to break down food proteins, fats, and complicated carbohydrates.
Forms of Hydrolysis:
There are several forms of hydrolysis, and we're going to briefly look at them below.
Salts: This is the type of hydrolysis that is most common. Salt hydrolysis normally refers to the salt reaction with water where the interaction between salt and water cations or anions is involved. A salt breaks down to form ions during hydrolysis, depending entirely or partially on the solubility factor.
Acid and Base: During the hydrolysis of esters or amides, acid-base-catalyzed hydrolysis can be observed. Here, when water or hydroxyl ion reacts with the carbon of the ester or amide carbonyl group where new compounds are formed, the process of hydrolysis occurs. Compounds of carboxylic acid groups are the results of both hydrolysis.
ATP: The majority of biochemical reactions in living organisms are in the form of ATP hydrolysis, which occurs with the aid of catalyst-acting enzymes. The catalytic activity of enzymes enables proteins, lipids, oils, fats and carbohydrates to be hydrolyzed or broken down.
 $ C{H_3}OH + PC{l_3} \to C{H_3}Cl\xrightarrow{{KCN}}C{H_3}CN\xrightarrow{{hydrolysis}}C{H_3}COOH $
Methyl alcohol Acetic acid
Alcohol in the presence of $ PC{l_3} $ gives $ R - Cl $ , which reacts with $ R - Cl $ , provides alkyl cyanide and hydrolysis provides carboxylic acid.
Option C- $ C{H_3}COOH $ is therefore right.

Note
Acetic acid is used in vinegar, pickled vegetables and sauce as an added sour agent, and as a raw material for spices. Acetic acid may be indicated by its group name, substance name, or abbreviated name according to the intent of use when used as a food additive.
