Which one of the following is expected to exhibit optical isomerism (\(en = \) ethylenediamine)
1 \(cis -\) \([Pt{(N{H_3})_2}C{l_2}]\)
2 \(trans -\) \([Co{(en)_2}C{l_2}]\)
3 \(trans -\) \([Pt{(N{H_3})_2}C{l_2}]\)
4 \(cis -\) \([Co{(en)_2}C{l_2}]\)
Explanation:
(d)
COORDINATION COMPOUNDS

\({[{\rm{EDTA}}]^{4 - }}\) is a:
1 Monodentate ligand
2 Bidentate ligand
3 Quadridentate ligand
4 Hexadentate ligand
Explanation:
(d)Ethylenediamine tetraacetate ion \((EDTA)\) They have six donor atoms. poly dentate ligands have flexidentate character. It is not necessary that all the donor atoms present in the polydentate ligands should form co-ordinate bonds with central metal atom or ion.
COORDINATION COMPOUNDS
28820
Which of the following statements is incorrect ?
1 In \({K_3}[Fe{(CN)_6}],\) the ligand has satisfied only the secondary valency of ferric ion.
2 In \({K_3}[Fe{(CN)_6}],\) the ligand has satisfied both primary and secondary valencies of ferric ion.
3 In \([Cu{(N{H_3})_4}]S{O_4},\) the ligand has satisfied only the secondary valency of copper.
4 Both \((a)\) and \( (c)\)
Explanation:
(d) In \({K_3}[Fe{(CN)_6}]\) the ligand are negative which is present in coordination spheres shows a dual behaviour. It may satisfied both primary & secondary valencies while neutral ligand satisfied only secondary valencies.

Explanation:
(a)Cis Isomer of \([Pt{(N{H_3})_2}C{l_2}]\) is used as an anticancer drugs for treating several type of malignant tumours. When it is injected into the blood stream the more reactive \(Cl\) groups are lost so the \(Pt\) atom bonds to a \(N\) atom in guanosine (a part of \( DNA\)) This molecule can bond to two different guanosine units & by bridging between them it upsets the normal reproduction of \( DNA.\)
