Which of the following species participate in sulphonation of benzene ring?
1 $\mathrm{H}_{2} \mathrm{SO}_{4}$
2 $\mathrm{SO}_{3}$
3 $\mathrm{HSO}_{3}^{-}$
4 $\mathrm{SO}_{3}^{-}$
Explanation:
(B): Sulphonation of involves the replacement of hydrogen atom in the ring by sulphoric acid $\left(\mathrm{SO}_{3} \mathrm{H}\right)$ group. Benzene can be sulphonated by treating it with turning sulphuric acid. $\mathrm{H}_{2} \mathrm{SO}_{4}+\mathrm{H}_{2} \mathrm{SO}_{4} \rightleftharpoons \mathrm{H}_{3} \mathrm{O}^{\oplus}+\mathrm{HSO}_{4}^{\ominus}+\stackrel{\oplus}{\mathrm{S}} \mathrm{O}_{3}$ $\mathrm{SO}_{3}$ is resonance hybrid.

Which one of the following gives sooty flame on combustion?
1 $\mathrm{C}_{2} \mathrm{H}_{4}$
2 $\mathrm{CH}_{4}$
3 $\mathrm{C}_{2} \mathrm{H}_{6}$
4 $\mathrm{C}_{6} \mathrm{H}_{6}$
Explanation:
(D): Aromatic compound $\mathrm{C}_{6} \mathrm{H}_{6}$ give sooty flame on combustion. $\mathrm{C}_{6} \mathrm{H}_{6}$ is a aromatic compound and give sooty flame on combustion. - $\mathrm{CH}_{4}, \mathrm{C}_{2} \mathrm{H}_{4}$ and $\mathrm{C}_{2} \mathrm{H}_{6}$ are aliphatic compound which do not give sooty flame during combustion.
