Question

Which of the following is not a use of Benzene?
A. Motor fuel
B. Dry cleaning
C. Preparation of gammexane
D. Preparation of acetic acid

Answer 1

Benzene can be formed from both natural processes and human activities. Natural sources of benzene include forest fires, bacteria etc. Some industries use benzene to make other chemicals which are further used to make plastics, resins and synthetic fibers.

Complete step by step answer:
Benzene is an organic compound with molecular formula ${C_6}{H_6}$, it is composed of six carbon atoms joined in a planar ring with one hydrogen attached to each carbon atom. It can also be addressed as a hydrocarbon as it has only carbon and hydrogen atoms.
Benzene can be used for printing, painting, rubber, dry cleaning, adhesives and coatings, detergents, pharmaceutical drugs, preparation and use of inks in the graphic arts industries etc. It is also used as fuel. Benzene is also a natural part of crude oil, gasoline, and cigarette smoke.
It is used in the preparation of gammexane, as double bonds in benzene turn into single bonds with chlorine atom extra for each carbon atom.
But acetic acid cannot be formed by benzene as it is formed by oxidation of ethanol.

Hence, the option D is the correct answer.

Note: Benzene is commonly used as a solvent in many industrial, commercial and research. Manufacturers use products which contain benzene as solvents in various production stages and it is used in manufacturing chemical products and plastic products. Some examples include resins, synthetic products such as nylon, Styrofoam etc. Do not confuse benzene with cyclohexane. Cyclohexane has no double bonds while benzene has 3 double bonds.
