उत्तर
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.
