| Assertion: Thiophene present in commercial benzene as an impurity can be removed by shaking the mixture with cold concentrated \[{{H}_{2}}S{{O}_{4}}\]. |
| Reason: Thiophene is a heterocyclic aromatic compound. |
| Read the assertion and reason carefully to mark the correct option out of the options given below: |
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.
D) If the assertion and reason both are false.
E) If assertion is false but reason is true.
Correct Answer: C
Solution :
[b] On shaking with concentrated \[{{H}_{2}}S{{O}_{4}}\] thiophene being more reactive undergoes sulphonation and the thiophene-2-sulphonic acid thus formed dissolves in concentrated \[{{H}_{2}}S{{O}_{4}}\]
