NEETChemistryAmines
Given below are two statements; one is labelled as Assertion (A) and the other is labelled as Reason(R). Assertion : The correct boiling point order of isomeric amines is - Primary > Secondary > Tertiary Reason : The intermolecular H-bonding in primary amine is maximum due to two hydrogen available for more association but in tertiary amine there is no hydrogen available for H -bond. In the light of the above stateme
Options
- ABoth (A) and (R) are correct and (R) is the correct explanation of (A).
- BBoth (A) and (R) are correct but (R) is not the correct explanation of (A).
- C(A) is correct but (R) is not correct.
- D(A) is not correct but (R) is correct.
Correct answer
A. Both (A) and (R) are correct and (R) is the correct explanation of (A).
Step-by-step solution
Assertion (A): The correct boiling point order of isomeric amines is - Primary > Secondary > Tertiary. This statement is correct. Primary amines generally have higher boiling points than secondary and tertiary amines due to stronger hydrogen bonding. Reason (R): The intermolecular H -bonding in primary amine is maximum due to two hydrogens available for more association, but in tertiary amine, there is no hydrogen available for H -bond. This statement is also correct. Primary amines can form more hydrogen bonds bec
