Question

Molecules with a positive and negative side (permanent dipole ---> always has partial pos a partial neg charge)

Answer 1

Polar molecules have a positive and negative side, resulting in permanent dipoles. These molecules have dipole-dipole interactions, where the positive end of one molecule attracts the negative end of another.

Step-by-step explanation:

Molecules that have a positive and negative side are called polar molecules. These molecules have permanent dipoles, where one end of the molecule is partially positive and the other end is partially negative. This is due to an unequal distribution of electron density throughout the molecule. Dipole-dipole interactions occur between polar molecules, where the positive end of one molecule attracts the negative end of another molecule. Examples of polar molecules include water (H2O) and hydrogen fluoride (HF).
