In order to have dipole-dipole attractions, a molecule must have a permanently uneven distribution of electrons so only polar molecules have dipole-dipole attractions.

Here's why:

1. Dipole-dipole attractions occur when the positive end of one polar molecule is attracted to the negative end of another polar molecule.

2. Polar molecules are those with a permanent dipole, meaning they have a positive charge on one end and a negative charge on the other. This happens when there is an uneven distribution of electrons within the molecule, usually because one atom is more electronegative than the other(s).

3. Nonpolar molecules, on the other hand, have an even distribution of electrons and therefore do not have a permanent dipole. As a result, they cannot have dipole-dipole attractions.

4. While it's true that all molecules have electrons, not all molecules have an uneven distribution of electrons. Therefore, not all molecules can have dipole-dipole attractions.

5. Hydrogen bonding, which involves a hydrogen atom bonded directly to N, O, or F, is a specific type of dipole-dipole attraction, but it's not the only type. Other polar molecules can also have dipole-dipole attractions.
