Vedclass · Answer

(B) The ease of diazotisation depends on the basicity of the amine and the stability of the resulting diazonium salt. $ (A) $ is an aliphatic amine,which forms highly unstable diazonium salts that decompose immediately. Thus,it has the lowest tendency for diazotisation. Among aromatic amines,electron-donating groups increase the electron density on the nitrogen atom,increasing basicity and facilitating diazotisation. Electron-withdrawing groups decrease electron density,making diazotisation more difficult. $ (B) $ is aniline. $ (C) $ has an $ -OCOCH_3 $ group at the meta position,which is electron-donating by resonance but electron-withdrawing by induction. Overall,it is slightly activating or neutral. $ (D) $ has an $ -COCH_3 $ group at the ortho position,which is a strong electron-withdrawing group,significantly reducing the basicity of the amine and making diazotisation difficult. Therefore,the increasing order of diazotisation is $ (A) < (D) < (B) < (C) $.

The increasing order of diazotisation of the following compounds is:
