Which of the following orders are correct regarding their covalent bond character?
i. KF \(<\) KI
ii. SnCl2 \(<\) SnCl4
iii. NaCl \(<\) CuCl
Show Hint
i, ii, iii
i, iii only
ii, iii only
i, ii only
The Correct Option is A
Solution and Explanation
Step 1: Analyze the molecular geometries.
Set i: Both molecules are tetrahedral, sharing identical electron pair geometries.
Set ii: Both molecules have a pyramidal structure, albeit \(<NF_3>\) with bonding pairs and \(<XeO_3>\) with lone pairs affecting the structure.
Set iii: Both are linear, having the simplest geometric arrangement.
Step 2: Comparison with Set iv. Set iv does not contain isostructural molecules due to the different spatial arrangements (\(<SF_4>\) see-saw vs. \(<XeF_4>\) square planar).
