The correct statements from following are: Choose the correct answer from the options given below:
- B, C only
- B, D only
- A, C only
- A, D only
Answer
(1) B, C only
Solution
A: CFT treats ligands as point charges, so anionic ligands should split most — yet F-, Cl- are weak-field ligands. CFT cannot explain this ⇒ A is false
B: a stated limitation of VBT (no quantitative account of kinetic/thermodynamic stability) ⇒ B is true
C: CN- (strong field) pairs the 3d electrons of Ni2+ ⇒ dsp2 ⇒ C is true

D: cis- [PtCl2(en)2]2+ has no plane of symmetry ⇒ d and l forms (2 isomers) ⇒ D is false

∴ B, C only
