Question

Nitroalkanes have high boiling point because:

• A. they have weak dipole-dipole interaction.
• B. they have strong dipole-dipole interaction.
• C. both $A$ and $B$
• D. none of these

Answer 1

Answer: (B)

they have strong dipole-dipole interaction.

Nitroalkanes have high boiling point, because they have strong dipole-dipole interaction. For example, the boiling point of nitro methane is 374 K. It is same as the boiling point of water. Nitro methane is highly polar. It has significant electrostatic attraction and possess high boiling point.
