Match List-I with List-II and choose the correct answer from the options given below:
Column I
- A. Nitrogen atom
- B. Fluorine molecule
- C. Oxygen molecule
- D. Xenon atom
Column II
- I. Paramagnetic
- II. Most reactive element in group 18
- III. Element with highest ionisation enthalpy in group 15
- IV. Strongest oxidising agent
Correct answer: A → III, B → IV, C → I, D → II
Detailed Solution
Nitrogen atom has the highest ionisation enthalpy in group 15 (A-III). Fluorine molecule is the strongest oxidising agent (B-IV). Oxygen molecule is paramagnetic (C-I). Xenon is the most reactive noble gas in group 18 (D-II).
