JEE Main 8 April 2024, Shift 1, Chemistry Q74

Question 74 of 90 in this shift, Chemistry question 14 of 30, Section A.

Given below are two statements: Statement I: [figure: Compound A, a benzene ring bearing Cl, and two NO2\mathrm{NO_2} groups] IUPAC name of Compound A is 4-chloro-1,3-dinitrobenzene. Statement II: [figure: Compound B, a benzene ring bearing NH2\mathrm{NH_2}, CH3\mathrm{CH_3} (adjacent) and C2H5\mathrm{C_2H_5} (para to NH2\mathrm{NH_2})] IUPAC name of Compound B is 4-ethyl-2-methylaniline. In the light of the above statements, choose the most appropriate answer from the options given below:

The figure, in words

Compound A: benzene ring with Cl at the top-right position, one NO2 on the right side and an O2N group at the left (nitro groups meta to each other, Cl ortho to one nitro). Compound B: benzene ring with NH2 at top, CH3 on the adjacent top-right carbon, and C2H5 at the bottom (para to NH2).
