Which of the following statements is/are true?

Answer»

In ferrocyanide ion, the EFFECTIVE atomic number is 36
Chelating ligands are ATLEAST bidentate ligands
`[CrCl_(2)(CN)_(2)(NH_(3))_(2)]^(2+)" and "[CrCl_(3)(NH_(3))_(3)]` both have `d^(2)sp^(3)` hybridisation
As the number of rings in complex increases, stability of complex (CHELATE) also increases

Solution :`(Mn_(2)(CO)_(10))` total electrons `=25xx2+10xx2=70`

Hence `Mn_(2)(CO)_(10)` is neither an O.A. or R.A.
