JEE Main 18 March 2021, Shift 2, Chemistry Q48

Question 48 of 90 in this shift, Chemistry question 18 of 30, Section A.

[figure: reaction scheme] Consider the given reaction, percentage yield of :

The figure, in words

Drawn: benzene ring with NH2, arrow labelled HNO3, H2SO4 / 288 K, then three products joined by +: A = benzene ring with NH2 and NO2 on adjacent ring carbons (ortho); B = ring with NH2 and NO2 on ring carbons separated by one carbon (meta); C = ring with NH2 at top and NO2 at bottom (para); labelled A, B, C beneath.
  1. (1)A > C > B
  2. (2)C > A > B
  3. (3)B > C > A
  4. (4)C > B > AOfficial answer
