Which one of the following species is involved in the sulphonation of aromatic hydrocarbons?
1 \(\mathrm{HSO}_{4}^{-}\)
2 Dil. \(\mathrm{H}_{2} \mathrm{SO}_{4}\)
3 \(\mathrm{SO}_{2}\)
4 \(\mathrm{SO}_{3}\)
Explanation:
CHXI13:HYDROCARBONS

The reaction \({{\text{C}}_{\text{6}}}{{\text{H}}_{\text{6}}}{\text{ + C}}{{\text{H}}_{\text{3}}}{\text{Cl}}\xrightarrow{{{\text{AlC}}{{\text{l}}_{\text{3}}}}}{\text{HCl + }}{{\text{C}}_{\text{6}}}{{\text{H}}_{\text{5}}}{\text{C}}{{\text{H}}_{\text{3}}}\) is called
1 addition reaction
2 Friedel-craft acylation
3 Friedel-craft alkylation
4 Friedel-craft benzoylation
Explanation:
When benzene react with alkyl chloride in the presence of anhydrous \({\rm{AlC}}{{\rm{l}}_{\rm{3}}}\), then methyl group is substituted in benzene ring. This reaction is called as Friedel-Craft's alkylation.
CHXI13:HYDROCARBONS

Statement A : Nitration of benzene with nitric acid requires the use of concentrated sulphuric acid. Statement B : The mixture of concentrated sulphuric acid and concentrated nitric acid produces the electrophile, \(\mathrm{NO}_{2}^{+}\).
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
Explanation:
The reaction is given below: So, the option (3) is correct.
