Assertion : acts as a powerful oxidising agent. Reason : atom in contains no lone pair of electrons.
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:
Sulfur trioxide is a strong oxidizing agent because of its high electron affinity, enabling it to readily accept electrons and induce oxidation reactions by extracting electrons from other substances. Sulphur atom in has no lone pair of electron on ' ' atom. Therefore, option (2) is correct.

Select the periodic property which is not regular in halogen family on moving down the group? (I) Ionization energy (II) Electron gain enthalpy (III) Size (IV) Electronegativity
1 I and II
2 I, III, and IV
3 II and IV
4 Only II
Explanation:
Electron gain enthalpy shows an irregular trend in halogens. Chlorine has higher electron gain enthalpy than fluorine. The correct order is
