Assertion (A): In a homologous series of alcohols, the formula for the second member is C2H5OH and the third member is C3H1OH.Reason (R): The difference between the molecular masses of the two consecutive members of a homologous series is 144.(a) Both A and R are true and R is the correct explanation of the Assertion.(b) Both A and R are true but R is not the correct explanation of the Assertion.(c) A is true but R is false.(d) A is false but R is true.
Correct Answer: (c) 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. Therefore, A is true but R is false.
