_” STRUCTURE AND THE BONDING “_

Amide simplest is a derivative of ammonia in which one hydrogen atom has been replaced by an acyl group. In general, amides are represented as RC (O) NH2.

Amida can be derived from primary amines (R'NH2) by the formula RC (O) NHR '. Amide also generally come from the secondary amine (R'RNH) by the formula RC (O) NR'R. Amida is usually considered as derivatives of carboxylic acids in which the hydroxyl group has been replaced by an amine or ammonia.

_” MELTING POINT “_.

Melting point of amide is high for the size of the molecules because they can form hydrogen bonds.

Hydrogen atoms in the NH2 group positive enough to form hydrogen bonds with the lone pair on the oxygen atom of another molecule.
