Benzene is heated with mixture of concentrated `HNO_(3)` and concentrated `H_(2)SO_(4)` at `60^(@)C` the product of this reaction is then treated with `Cl_(2)` in the presence of anhydrous `FeCl_(3)` the major product obtained in the final step is

Options

A. 2-chloro-1-nitrobenzene
B. 3-chloro-1nitrobenzene
C. 4-chloro-1-notrobenzene
D. equal amount of (1) and (3)

Answer

B

Explanation

Step 1 involves direct nitration ste3p 2 leads to direct chlorination of nitrobenzene. The `-NO_(2)` is strongly deactivating and exerts poerful meta orienting effect to give 3-chlorolnitrobenzene (or correctly 1-chloro-3-nitrobenzene).
