Question

Assertion: The functional group present in alcohols is -OH.
Reason: It is the same group present in water, hence water and alcohol have similar properties.

• A. Both assertion and reason are true and the reason is the correct explanation of assertion.
• B. Both assertion and reason are true but the reason is not the correct explanation of assertion.
• C. Assertion is true but reason is false.
• D. Both assertion and reason are false.

Answer 1

The correct option is C Assertion is true but reason is false.

Not all alcohols have properties similar to that of water. Alcohols that have less than five carbon atoms in their hydrocarbon chain have properties similar to that of water due to the hydroxyl group, i.e, in terms of polarity, solubility and ability to form hydrogen bonds with other alcohol molecules. Alcohols that have more than six carbon atoms have properties different from that of water since the hydrocarbon chain affects the hydroxyl group due to its large carbon chain making it less soluble in water and the difficulty to form hydrogen bonds with other alcohols.
