Step-by-step solution

When 2,4,6-triaminobenzoic acid is heated with aqueous acid ( H ₃ O ^+ , ), it undergoes decarboxylation followed by hydrolysis. In the acidic medium, the - NH ₂ groups are protonated to - NH ₃^+ . These strongly electron-withdrawing groups facilitate decarboxylation upon heating, yielding 1,3,5-triaminobenzene. Unlike typical aromatic amines, 1,3,5-triaminobenzene is susceptible to hydrolysis because it can tautomerize to an intermediate triimine (cyclohexane-1,3,5-triimine). This triimine is readily hydrolyzed by
