Explanation
The observed magnetic moment value (\mu _{abs}) is higher than calculated magnetic moment value (\mu _{cal}) for which of the following species?
The slight irregularities in size have been ascribed to:
Which one of the following has largest number of stereoisomers?
Match the correct pairs of isomers with their examples.
A)Ionisation (a) Pt(NH_{3})_{2}Cl_{2}][Pt(NH_{3})_{4}]
[PtCl_{4}]
B) Linkage (b) [Cr(NH_{3})_{6}][Co(CN)_{6}] & [Co(NH_{3})_{6}[Cr(CN)_{6}]
C)Coordination (c) [Co(NH_{3})_{5}(NO_{2})]Cl_{2} & [Co(NH_{3})_{5}(ONO)]Cl_{2}
D)Polymerisation (d) [Co(SO_{4})(NH_{3})_{5}]Br & [Co(Br (NH_{3})_{5}]SO_{4}
Platinum is bonded with two types of ligands,
Ethylenediamine which is a bidentate ligand is two in number hence 2\times2 =4
Chloride which is an unindented ligand is two in number hence 1\times2 = 2
Co-ordination no.= 6
Oxidation state of central metal atom :x+ 0-2 = x = 2
