Question

Which combination of characteristics is most likely to be associated with molecules having strong dipole-dipole interactions?
I. Polar bond
II. Asymmetric shape
III. Relatively low boiling point
IV. Large surface area

• A. I and III
• B. II and IV
• C. I and II
• D. III and IV

Answer 1

Answer: (C)

I and II

Option $C$ is correct.

$\Rightarrow$ For dipole-dipole interaction it needs or polar bond.

$\Rightarrow$ If the molecule having asymmetric shape then dipole momentum won't be zero then only dipole-dipole interaction possible.
