Low molecular weight amides are soluble in water due to the formation of hydrogen bonds. primary amides have higher melting and boiling points than secondary and tertiary amides. Anilide is an amide derived from aniline by substitution of an acyl group for the hydrogen of NH2. Acetanilide is from acetic acid and aniline. Acetanilide is an odourless, white flake solid or crystalline powder (pure form); soluble in hot water alcohol, ether, chloroform, acetone, glycerol, and benzene;; melting point 114 C and boiling point 304 C; can undergo self-ignite at 545 C, but is otherwise stable under most conditions. Acetanilide which can be obtained by acetylation of aniline undergoes nitration at low temperature and yields highly the para-nitro products. Acetyl group can then be removed by acid-catalyzed hydrolysis to yield para-nitroaniline. Although the activating affection of the amino group can be reduced, the acetyl derivative remains an ortho/para-orientation and activating substituent. Examples of aromatic anilide are benzanilide, C6H5NHCOC6H5 or Carbanilide (N,N'-diphenylcarbamide). Some structural amides are; * Acetamides * Acrylamides * Anilides * Benzamides * Naphthylamides * Formamides * Lactams * Salicylamides * Sulfonamides * Thioamides * Fatty amidesAn amide is hydrolyzed to yield an amine and a carboxylic acid under strong acidic conditions. The reverse of this process resulting in the loss of water to link amino acids is
