Question

Which of the following compounds has dipole-dipole intermolecular forces?

Answer 1

All of the following compounds have dipole-dipole intermolecular forces:

1. HCl
2. CH3Cl
3. NO2
4. HF
5. CH2Cl2

Dipole-dipole forces occur between polar molecules that have a permanent dipole moment. These forces involve the attraction between the positive end of one dipole and the negative end of another, leading to the alignment of the molecules and the attraction between them.
