Question

Which of the following statements is/are correct about the following reactions?

• A. path I is feasible.
• B. path II is feasible.
• C. PhCl cannot be trinitrated because CI and two $N{O}_2$ atoms deactivate the ring towards further SE reaction.
• D. 2, 4-Dinitrophenol can be nitrated beacuse the two deactivating $N{O}_2$ groups prevent ring oxidation.

Answer 1

Answer: (A), (C), (D)

path I is feasible.
PhCl cannot be trinitrated because CI and two $N{O}_2$ atoms deactivate the ring towards further SE reaction.
2, 4-Dinitrophenol can be nitrated beacuse the two deactivating $N{O}_2$ groups prevent ring oxidation.

The statement (B) is incorrect and the statements A, C and D are correct.
Path I is feasible.
Path II is not feasible.
PhCI cannot be nitrated because CI and two nitro groups deactivate the ring towards further aromatic electrophilic substitution reaction.
2, 4-Dinitrophenol can be nitrated because the two deactivating nitro groups prevent ring oxidation.
