Question

Assertion (A): The members of a homologous series can be prepared by using the same general method.

Reason (R): The members of a homologous series have the same physical properties.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.

Options

• (1)

• (2)

• (3)

• (4)

Answer 1

(3)

Explanation:

The members of a homologous series have the same functional group and similar chemical properties, so they can generally be prepared by the same general method. Therefore, the Assertion (A) is true.

Members of a homologous series do not have the same physical properties; their physical properties change gradually with increasing molecular mass. Therefore, the Reason (R) is false.

Hence, A is true but R is false.
