Which of the following statement is/are correct? I. The ligand thiosuphato, S 2 O 3 2 - can give rise to linkage isomers. II. In metallic carbonyls the ligand CO molecule acts both as donor and acceptor. III. The complex P t P y N H 3 N O 2 C l B r I exists in eight different geometrical isomeric forms IV. The complex ferricyanide ion does not follow effective atomic number (EAN) rule.
Options
- AI and II only
- BII and IV only
- CI, II and III
- DI, II and IV
Correct answer
D. I, II and IV
Step-by-step solution
S 2 O 3 2 - can give rise to linkage isomers as it can coordinate through both O and S atoms. Ligand CO molecule acts both as donor and acceptor by donating pi electron and accepting electron form metal into its vacant π * molecular orbital. Hence here I and II are correct and in case of ferricyanide ion effective atomic number is 35 so IV is also correct.
