Question

Paraffin wax is
(a) Ester
(b) Acid
(c) Monohydric alcohol
(d) Cholesterol

Answer 1

Hint It is an acid derivative compound with at least one OH group replaced by an alkyl group. They are usually produced from the substitution reaction of an alcohol and a carboxylic acid group.

Complete answer:
A colorless soft solid which is derived from compounds consisting of hydrocarbons is paraffin wax. Generally, waxes are esters. Examples are coal, petroleum products. At room temperature it occurs a solid at temperatures above 37℃, it starts melting. Lubrication, manufacturing of candles, and insulation are some of the applications of paraffin wax. It is soluble in benzene, ether, and some esters. Removing the oil from stack wax is the first step in the manufacturing of paraffin wax.

Additional information:
- For storing heat and a heat of fusion, paraffin wax is an excellent material.
- By the process of crystallization, oil is separated. By mixing one or more solvents such as ketone, slack wax is heated and then cooled which leaves oil and wax is crystallized out of the solution. Now, this oil is filtered. The resulting product is called paraffin wax after the solvent is recovered from distillation.
- Paraffin wax is used for medical purposes for relieving the pain in osteoarthritis, rheumatoid arthritis, fibromyalgia, and other joint pains. It also helps in increasing the blood flow, decreasing the stiffness of the joints, muscle relaxation, minimizing muscle spasms, and reducing inflammation.

So, the correct answer is ‘Esters’

Note: Paraffin wax when used by people with sensitive skin, it causes heat rash. Poor blood circulation, numbness, diabetes, and rashes on open sores are some of the side effects of paraffin wax.
