Dicarboxylic acids have two carboxylic groups, e.g.,

Acidity of dicarboxylic acid depends upon the stability of intermediate ion and upon the distance between two carboxylic groups. Shorter the distance between two carboxylic groups, greater is the acidic character. Melting point of these acids depends on the symmetry. Greater the symmetry, higher will be the melting point.

A

Malonic acid

B

Succinic acid

C
