Answer the following questions about intermolecular forces.

Question

Why do molecules exhibit dipole-dipole forces? Select the single best answer.
Because the molecules are nonpolar?
• Because the molecules can hydrogen bond.?
• Because the molecules have a symmetrical electron distribution.?
• Because the molecules have strong intramolecular attractions.?
Because the molecules are polar?.

Answer 1

The single best answer is: Because the molecules are polar.

Dipole-dipole forces occur between molecules that have permanent dipoles due to differences in electronegativity between the atoms they consist of, making them polar.
