Question
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.
Options
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.

Solution
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.
