Question

Match List-I with List-II:

• A. A-IV, B-I, C-III, D-II
• B. A-II, B-III, C-IV, D-I
• C. A-IV, B-I, C-II, D-III
• D. A-III, B-IV, C-II, D-I

Hint:

The trend in ionic radii follows the charge and size of ions. Ionisation energy generally increases across a period and decreases down a group. Metallic character decreases across a period and increases down a group. Electronegativity increases across a period and decreases down a group.

Answer 1

The Correct Option is C

Ionic radii: \( \text{Al}^{3+} <\text{Mg}^{2+} <\text{Na}^+ <\text{F}^- \) Ionisation energy: \( B <C <O <N \) Metallic character: \( B <\text{Al} <\text{Mg} <K \) Electronegativity: \( \text{Si} <\text{P} <\text{S} <\text{Cl} \) Thus, the correct match is: \[ \text{A-IV, B-I, C-II, D-III} \]
