Sodium benzoate: Polarity; Functions and Applications
Sodium benzoate is a polar chemical. This is due to the polar covalent bond between the carbon and oxygen atoms in the carbonyl group (-CO) and the carbon and oxygen atoms in the carboxyl group (-COO-

2-Naphthol: Polarity; Solubility and Uses
2-Naphthol is a polar molecule. Since naphthol contains hydroxyl groups, it is a very polar molecule, and the oxygen atom attracts the electron density to itself through bonds.
