JEE Main 2 April 2026, Shift 1, Chemistry Q68

Question 68 of 75 in this shift, Chemistry question 18 of 25, Section A.

Consider the three aromatic molecules (P, Q and R) whose structures have been given below : [figure: structures P, Q, R] The correct order regarding the reactivity of these compounds with Ph−N(+)≡N Cl(−)\mathrm{Ph{-}\overset{(+)}{N}{\equiv}N\,Cl^{(-)}} under optimum but slightly acidic medium is :

The figure, in words

Three structures: P = benzene ring bearing N(Me)2 (lone pair shown on N); Q = same with one Me on the ring ortho to N(Me)2; R = same with Me at both ortho positions.
