CH2O has a central carbon atom that forms two single bonds with the two hydrogen atoms and a double bond with the oxygen atom. Draw Lewis structures for each of the five molecules. The NH3 molecule is a polar molecule since it has three dipoles due to three bonds that do not cancel each other. This leads to a strong pull of the electron pair on both sides (because both the elements are highly electrophile), altering the otherwise straight bond. When two atoms forming a covalent bond have an unequal electric charge distribution, the bond is said to be polar. Ammonia shows the basic character of the material. molecule or polyatomic ion polar or nonpolar? >. Ammonia gas is highly soluble in water, producing ammonium ions, and polar molecules are more readily mixed with other polar molecules.
