Question

Assertion (A): Following are the members of a homologous series:

CH₃OH, CH₃CH₂OH, CH₃CH₂CH₂OH

Reason (R): A series of compounds with same functional group but differing by - CH₂ - unit is called a homologous series.

Options

• Both (A) and (R) are true and (R) is correct explanation of the assertion.

• Both (A) and (R) are true and (R) is correct explanation of the assertion.

• (A) is true but (R) is false.

• (A) is false but (R) is true.

Answer 1

Both (A) and (R) are true and (R) is correct explanation of the assertion.

Explanation:

Both A and R are true and R correctly explains A. Methanol, ethanol and propanol all have the same functional group (–OH) and each successive member differs by a –CH₂– unit, so they form a homologous series.
