Which of the following correctly gives the decreasing order of rate of nitration?

A $C X_{6} H X_{5} CH X_{3} > C X_{6} H X_{6} > C X_{6} H X_{5} NO X_{2} > C X_{6} H X_{5} Cl$
B $C X_{6} H X_{5} CH X_{3} > C X_{6} H X_{6} > C X_{6} H X_{5} Cl > C X_{6} H X_{5} NO X_{2}$
C $C X_{6} H X_{6} > C X_{6} H X_{5} CH X_{3} > C X_{6} H X_{5} Cl > C X_{6} H X_{5} NO X_{2}$
D $C X_{6} H X_{5} CH X_{3} > C X_{6} H X_{5} Cl > C X_{6} H X_{6} > C X_{6} H X_{5} NO X_{2}$

Answer: B

Toluene is activated by the methyl group, so it is faster than benzene. Chlorobenzene is deactivated (-I outweighs +M) and nitrobenzene is strongly deactivated (-I and -M). The order is toluene > benzene > chlorobenzene > nitrobenzene.

More questions on Electrophilic aromatic substitution: mechanism and directing effects

In electrophilic aromatic substitution of benzene, the rate-determining step is NEET level
Benzene reacts with CH3COCl and anhydrous AlCl3 to give NEET level
Heating nitrobenzene with concentrated HNO3 and concentrated H2SO4 gives mainly JEE Main level
Anisole is treated with Br2 in ethanoic acid (no catalyst). The major product is JEE Main level
Benzene reacts with 1-chloropropane in the presence of anhydrous AlCl3. The major product is JEE Main level
Benzoic acid is treated with Br2 and FeBr3. The major product is JEE Main level
