For chlorobenzene with nitro groups at ortho and para positions to convert to picric acid we need warm h20 and naoh right
A
Yes, warm H2O and NaOH are sufficient.
B
No, additional nitration is required.
C
The reaction requires acidic conditions, not basic.
D
Only warm water is needed.
Answer
No. Additional nitration is required.
Explanation
Solution
The starting material, 1-chloro-2,4-dinitrobenzene, reacts with NaOH and warm H2O via nucleophilic aromatic substitution to form 2,4-dinitrophenol. Picric acid is 2,4,6-trinitrophenol. To obtain picric acid, a third nitro group must be introduced at the 6-position, which requires a subsequent nitration step with concentrated nitric acid. Therefore, warm H2O and NaOH alone are not sufficient.
