Q7: Among isomeric amines, tertiary amines have the lowest boiling points because: (a) they have highest molecular mass (b) they are most basic in nature (c) they are more polar in nature (d) they do not form hydrogen bonds
Answer: (d) they do not form hydrogen bonds Explanation: Hydrogen bonds can be formed by primary and secondary amines, but not by tertiary amines. As a result, they have the lowest boiling points.
