Toluene reacts with halogen in presence of iron (III) chloride giving ortho- and para- halo compounds. The reaction is
1 free radical addition reaction
2 electrophilic elimination reaction
3 nucleophilic substitution reaction
4 electrophilic substitution reaction
Explanation:
Toluene reacts with halogen in presence of Iron (III) chloride giving ortho and para halocompounds, the reaction is electrophilic substitution reaction. The "H" atom or aromatic nucleus is replaced with chlorine atom. The electrophile in this reaction is \(\mathrm{Cl}+\) ion obtained by the reaction of \(\mathrm{Cl}_{2}\) with \(\mathrm{AlCl}_{3}\).

Consider the nitration of benzene using mixed con. \(\mathrm{H}_{2} \mathrm{SO}_{4}\) and \(\mathrm{HNO}_{3}\). If a large amount of \(\mathrm{KHSO}_{4}\) is added to the mixture, the rate of nitration will be
1 Doubled
2 Faster
3 Slower
4 Unchanged
Explanation:
If large amount of \({\text{KHS}}{{\text{O}}_{\text{4}}}\) is added, concentration of \({\text{NO}}_{\text{2}}^{\text{ + }}\) and decrease the and hence the nitration will be slower.
