JEE Main 26 July 2022, Shift 1, Chemistry Q77

Question 77 of 90 in this shift, Chemistry question 17 of 30, Section A.

The correct stability order of the following diazonium salt is (A) [figure: benzene ring with +N2Cl−^{+}\mathrm{N_2Cl^-} at the top and OCH3\mathrm{OCH_3} at the bottom (para)] (B) [figure: benzene ring with N2+Cl−\mathrm{N_2^+Cl^-} at the top and NO2\mathrm{NO_2} at the bottom (para)] (C) [figure: benzene ring with N2+Cl−\mathrm{N_2^+Cl^-} only] (D) [figure: benzene ring with N2+Cl−\mathrm{N_2^+Cl^-} at the top and CN at the bottom (para)]

The figure, in words

Four benzene diazonium chlorides drawn in the stem: (A) para OCH3, (B) para NO2, (C) unsubstituted, (D) para CN.
