Any compound containing Nitrogen, Oxygen, Fluorine and Chlorine

#### Explanation:

These elements are highly electronegative because they attract more the bonded electrons, making them have a partially negative charge and the element bonded to it a partially positive charge.

Example- butan-1-ol

Butan-1-ol is a polar molecule because it has an -OH bond. Oxygen gets a partially negative charge $\delta -$ and hydrogen gets a partially positive charge $\delta +$.

This is why it can dissolve in water. Hydrogen bonding can occur between the hydrogen of the alcohol and the lone pair of the water molecule.
