Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
All dihydroxy benzene will have, higher boiling points than monohydroxy benzene. Also, among dihydroxy benzenes, $1, 2$,-di-hydroxy benzene has lowest boiling poirt due to intramolecular H-bonding.

Alcohols
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.
