Answer & Solution

Correct Answer

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

Step-by-step Solution

Detailed explanation

प्राथमिक संयोजकता \(=\) ऑक्सीकरण अवस्था द्वितीयक संयोजकता \(=\) उपसहसंयोजन संख्या संकुल प्राथमिक संयोजकता द्वितीयक संयोजकता (A) [Co(en)2Cl2]Cl 3 6 (B) [Pt(NH3)2Cl(NO2)] 2 4 (C) Hg[Co(SCN)4] 3 4 (D) [Mg(EDTA)]2- 2 6

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
