Question

Two statements are given - one labeled Assertion (A) and the other labeled Reason (R).
Assertion (A): In a homologous series of alcohols, the formula for the second member is C₂H₅OH and the third member is C₃H₇OH.
Reason (R): The difference between the molecular masses of the two consecutive members of a homologous series is 144.

विकल्प

• Both A and R are true and R is the correct explanation of the Assertion.

• Both A and R are true but R is not the correct explanation of the Assertion.

• A is true but R is false.

• A is false but R is true.

Answer 1

A is true but R is false.

Explanation:

In a homologous series of alcohols, the formula for the second member is C₂H₅OH and the third member is C₃H₇OH. The difference between the molecular masses of the two consecutive members of a homologous series is 14.
Hence, the correct answer is the assertion is true and Reason is false.
