Which of the following is most reactive towards nucleophilic substitution?

AChlorobenzene
B$$2, 4, 6$$ - Trinitro chlorobenzene
Correct Answer
C$$2, 4$$ - Dinitro chlorobenzene
D$$2$$ - nitro chlorobenzene

Solution

Compounds with more number of $$NO_2$$ ( at ortho and para) will perform the fastest nucleophilic substitution reaction.

Hence $$2,4,6$$ - trinitrochloro benzene is most reactive.

The order for reactivity is as shown in figure.

Option B is correct.
