Dicarboxylic acids have carboxylic group...

Dicarboxylic acids have carboxylic groups e.g.
HOOC-COOH,oxalic acid
HOOC`-CH_(2)-`COOH-Maloic acid
HOOC-`(CH_(2))_(3)`-COOH-Glutaric acid
HOOC,`(CH_(2))_(4)`-COOH,-Adipic acid
Acidity of dicarboxylic acids depends upon the stabillity of intermediate ion and upon the distance between two carboxylic groups. shorter the distance between two carboxylic groups, greater is the acididc character. Melting point of the acids depends on the symmetry. greater the symmetry, higher will be the mp. Dicarboxylic acids on heating give monocarboxylic acid, alkanes, cyclic ketones dependings on the conditions.

A
