Two statements are given below. Statement I: SnF ₄, PbF ₄ are ionic in nature Statement II: GeCl ₂ is more stable than GeCl ₄ The correct answer is
Options
- ABoth statements I & II are correct
- BBoth statements I & II are not correct
- CStatement I is correct, but statement II is not correct
- DStatement I is not correct, but statement II is correct
Correct answer
C. Statement I is correct, but statement II is not correct
Step-by-step solution
In group 14 , most of the MX ₄ are covalent in nature exceptions SnF ₄ and PbF ₄ because there is more electronegativity difference make the bond ionic. So statement I is correct. Ge electronic configuration : [ Ar ] 3 ~d ¹⁰ 4 ~s ^2 4 p ^2 and Ge ⁺⁴ oxidation is more stable because its allows germanium to achieve a full valence shell, which is energetically more favorable than having an incomplete valence shell in the Ge ⁺² oxidation state. 'So' only statement I is correct.
