Question

The boiling point of amines are higher than that of hydrocarbon because:

• A. they form inter molecular H-bonds
• B. they are polar
• C. they form ionic bonds
• D. both A and B

Answer 1

Answer: (D)

both A and B

Amines have higher boiling points than hydrocarbons, as C-N bond in amines is more polar than a C-C bond in hydrocarbons.

Due to the polar nature of amines it forms intermolecular H-bonds and exists as associated molecules.

Thus, its boiling point is higher than that of hydrocarbons.
