Decarboxylation of all six possible forms of diaminobenzoic acids C _ 6 H _ 3 ( NH _ 2 ) _ 2 COOH yields three products

Decarboxylation of all six possible forms of diaminobenzoic acids C _ 6 H _ 3 ( NH _ 2 ) _ 2 COOH yields three products C is a para isomer.

The melting point of para-isomer is comparatively higher than the corresponding ortho and meta-isomers , because of more symmetrical nature; it fits into crystal lattice more readily and so, close packing of molecules in crystal lattice increases the intermolecular force of attraction between molecules.

Hence $\left(C\right)$ has highest melting point that is $142 ° C$
