Direction for: In each of the following questions a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements mark the correct answer as
Assertion: A primary amine has higher boiling point than any tertiary amine. Reason: A tertiary amine has greater number of \[N-H\]bonds for H-bonding.A) If both Assertion: and Reason: are true and the Reason: is the correct explanation of the Assertion:
B) If both Assertion: and Reason: are true but the Reason: is not the correct explanation of the Assertion:
C) If Assertion: is true but Reason: is false
D) If both Assertion: and Reason: are false
Correct Answer: C
Solution :
Primary amines have two \[N-H\] bonds, thus have the ability of H-bonding while such an ability is not found in tertiary amines because of the absence of \[N-H\] bonds. Thus, primary amines have higher boiling point than tertiary amines having same molecular mass. Hence, Assertion: is true but Reason: is false.
