Verified By Collegedunia

The Correct Option is D

Solution and Explanation

The structure of

3

-chlorobutan-

2

-ol is

(C^{*}

= chiral carbon atom)
Since, 3-chlorobutane-2-ol contains

2

asymmetric (chiral) carbon atoms, thus, the number of optical isomers

=2^{n}=2^{2}=4

What is Alcohol?

Alcohol is a derivative of water (H₂O) that has one, two, or more hydroxyl groups that are attached to a carbon atom of a hydrocarbon chain (an alkyl group). It is one of the most common organic compounds used in sweeteners, fragrances, and medicine.

Uses of Alcohol:

Ethanol is the alcohol used in alcoholic drinks. It can be used as an industrial methylated spirit where methanol is used very little in quantity as it can be dangerous.
It is used as fuel to produce carbon dioxide and water by the process of fermentation. Whereas methanol burns carbon dioxide and water to facilitate combustion.
Alcohol is an organic compound used as a solvent that is insoluble in water.
It can be used to lower the level of sugar.
Alcohol is used as a preservative in laboratories.
