Question
In Ni(CO)4 and Fe(CO)5 the oxidation state of Nickel is in the zero state only.
Solution
A. TRUE
Indicate the type of isomerism exhibited by the following complexes and draw structures for these isomers:
(i) K[Cr(H2O)2(C2O4)2], (ii) [Co(en)3Cl3,
(iii) [Co(NH3)5(NO2)]|NO3]2, (iv) [Pt(NH3)(H2O)Cl2]
Predict the number of unpaired electrons in the square planar [Pt(CN)4,]2– ion.
The hexaquo manganese(II) ion contains five unpaired electrons, while the hexacynoion contains only one unpaired electron. Explain using crystal field theory.
Identify the ligands from the following coordination compounds:
(a) [Co(en)2Cl(NO2)2]
(b) K[Co(CN)(CO2)(NO)]
(c) K3[Al(OH)6]
(d) [Co(H2O)2(NH3)4](OH)3
