Question

Assertion (A): A homologous series is a group of organic compounds having similar structure and similar chemical properties in which the successive compounds differe by CH₂ group. 

Reason (R): The organic compounds having same molecular formula but different structures are known as isomers.

विकल्प

• Both A and R are true and R is 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

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

Explanation:

Both statements are scientifically correct. The assertion accurately defines a homologous series, while the reason provides the exact definition of isomers. However, because structural isomerism is an entirely different concept from a homologous series, the reason does not explain the assertion.
