Which is/are weaker acid than water?
Updated On: Jun 6, 2022
- Alcohols
- Termirlal alkynes
- Mercaptans
- Both (a) and (b)
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Since the S-H bond in mercaptant is weaker than $O-H$ bond in alcohols. Therefore, mercaptans are stronger acid than alcohols. Further since both alkoxide ions $(RO^-)$ and acetylide ion $(RC\equiv C^-)$ react with $H_2O$ to give the corresponding alcohol and acetylene respectively. Hence, both alcohols and terminal alkynes are weaker acid than water.

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.
