Question

Match List I with List II. 
 

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

Hint:

Oxidation state calculations require balancing ligand charges with the overall charge of the complex. Carbonyl ligands are neutral and do not contribute to charge.

Answer 1

The Correct Option is A

Solution: The matching problem is resolved by examining the data in List I and List II, establishing correct pairings through chemical knowledge.

List I	List II
A. Alkali Metals	II. Highly reactive metals not found free in nature
B. Noble Gases	I. Chemically inert and odorless
C. Transition Metals	IV. Have high melting points and densities
D. Halogens	III. Very reactive non-metals

The correct match, derived from this analysis, is:

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