Large biological molecules are generally composed of a carbon skeleton (made up of carbon and hydrogen atoms) and some other atoms, including oxygen, nitrogen, or sulfur. In chemistry, the definition of a polar molecule, is a molecule that has a charge on one side of the molecule, that is not cancelled out. Teachers, learners, and connoisseurs of organic chemistry, thanks! HCHO will be most polar due to lowest electron density on carbon of carbonyl group. West Qurna 2, A.
