When acetylene and H2S react in the presence of hot Al2O3, the product formed is:
Correct answer: D. Thiophene
- A. Pyrrole
- B. Benzene
- C. Toluene
- D. Thiophene
Explanation
When acetylene reacts with H₂S in the presence of hot Al203 cyclization occurs. Sulfur gets incorporated into the ring structure. This reaction forms thiophene, a five-membered heterocyclic compound.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
