Assertion : Sulphuric acid is more viscous than water. Reason : Concentrated sulphuric acid has a great affinity for water.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Sulphuric acid molecules exhibit a strong tendency to associate with each other, primarily driven by a substantial number of intermolecular hydrogen bonds. \(\mathrm{H}_{2} \mathrm{SO}_{4}\) has great affinity for water and functions like a dehydrating agent. So option (2) is correct.

Statement A : In the preparation of \(\mathrm{H}_{2} \mathrm{SO}_{4}\) by contact process, \(\mathrm{SO}_{3}\) is not absorbed directly in water to form \(\mathrm{H}_{2} \mathrm{SO}_{4}\). Statement B : Acid fog is formed, which is difficult to condense.
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:
In the preparation of \(\mathrm{H}_{2} \mathrm{SO}_{4}\) by contact process, \(\mathrm{SO}_{3}\) is not absorbed directly in water to form \(\mathrm{H}_{2} \mathrm{SO}_{4}\) because acid fog is formed, which is difficult to condense.
