Assertion : Nitration of chlorobenzene leads to the formation of m-nitrochlorobenzene Reason : \(\mathrm{NO}_{2}\) group is a m-directing group.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Reactivity decreases as the number of \(-\mathrm{NO}_{2}\) group w.r.t. \(-\mathrm{Br}\) decreases. m - Nitrobromobenzene is, however, less reactive than the \({\rm{p}}\)-Nitrobromobenzene since the \(-\mathrm{NO}_{2}\) group at the m-position cannot stabilise the intermediate carbanion by resonance.

Assertion : Aryl halide gives a mixture of o- and p-products. Reason : Aryl halides undergo electrophilic substitutions more readily than benzene.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Halogens are somewhat deactivating but \(o\), p-directing. As a result, aryl halides undergo the usual electrophilic substitution reactions less readily than benzene.Therefore option (3) is correct.

The major product obtained in the following reaction is \({\text{Chlorobenzene }} + {\text{ chlorine }}\xrightarrow[{{\text{FeC}}{{\text{l}}_{\text{3}}}}]{{{\text{ Anhydrous }}}}\mathop {{\text{ Product }}}\limits_{{\text{ (Major) }}} \)
1 1,3,5-Trichlorobenzene
2 1,4-Dichlorobenzene
3 1,2-Dichlorobenzene
4 1,3-Dichlorobenzene
Explanation:
\(-\mathrm{Cl}\) group is \(\mathrm{o} / \mathrm{p}\) director and para will be major product.
