Hydrogen bonding between molecules of a aldehyde compound is not possible, since there is no readily available acidic proton. Polarity underlies a number of physical properties including surface tension, solubility, and melting and boiling points. What is Benzoic Acid? F2 is a diatomic molecule and is non-polar. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms. Benzoic acid is relatively non-toxic and is metabolized by the liver and excreted in the urine as hippuric acid. The polarity is a result of both a hydroxyl and a carboxyl group being attached to the carbon ring. Because of its large, hydrophobic benzene ring, benzoic acid is only slightly soluble in water when heated. Carboxylic acids donate hydrogen ions if a base is present to accept them. AsF5 is a nonpolar molecule despite it has five As-F polar bonds. Relevance. A molecule may be nonpolar either when there is an equal sharing of electrons between the two atoms of a diatomic molecule or because of the symmetrical arrangement of polar bonds in a more complex molecule.
