Be the first to answer this question. The dielectric constants of formamide and dimethylformamide are 111 and 37, respectively. Like the esters, solutions of amides in water usually are neutral—neither acidic nor basic. It needs energy to break the hydrogen bonds between amide molecules and between water molecules before they can mix - but enough energy is released again when the new hydrogen bonds are set up to allow this to happen. Amides which have smaller alkyl group have high solubility in water. They are nonconductors of electricity and solvents for both organic and inorganic substances. Both amines and amides are soluble in water due to the presence of a –NH group. Covalent amides, even those of … Tertiary amides, with the important exception of N,N-dimethylformamide, exhibit low solubility in water.
