Question

The boiling point of amines are higher than that of hydrocarbons because

• A. they form intermolecular H-bonds
• B. they are polar
• C. they form ionic bonds
• D. both (a) and (b)

Answer 1

The correct option is D both (a) and (b)

Amines have higher boiling points than hydrocarbons, as C-N in amines is more polar than a C-C bond in hydrocarbons.
Due to the polar nature of amines it forms intermolecular H-bonding and exists as associated molecules.
Thus, its boiling point is higher than that of hydrocarbons. Hence, the correct answer is option (d).
