Question

give reaction of sulphonation of thiophene​

Answer 1

Answer:

Fusion of thiophene with a benzene ring gives benzothiophene. Fusion with two benzene rings gives either dibenzothiophene (DBT) or naphthothiophene. Fusion of a pair of thiophene rings gives isomers of thienothiophene.

Answer 2

Answer:

The high reactivity of thiophene toward sulfonation is the basis for the separation of thiophene from benzene, which are difficult to separate by distillation due to their similar boiling points (4 °C difference at ambient pressure). Like benzene, thiophene forms an azeotrope with ethanol.

Chemical formula: C4H4S

Viscosity: 0.8712 cP at 0.2 °C; 0.6432 cP at 22.4 °C
