Q. Give the order of ease of decarboxylation of the following acids $C$
A) $I > II > III > IV$
B) $III > IV > II > I$
C) $IV > III > II > I$
D) $I > III > II > IV$
Explanation
(c)
In 2, 4, 6-tri-nitrobenzoic acid, the decarboxylation takes place most easily, because of $–I$ effect of nitro group, whereas in the dicarboxylic acid with one carbon atom having two carboxylic group it is also easier to remove$CO_{2}$. Hence, the order of ease of decarboxylation
