Explanation
O.N. of Mn in [MnO4]‒ is +7 which is achieved by losing all 3d5 and 4s2 electrons.
N in NH3 is sp3-hybridized, Pt in [PtCl4]2- is dsp2 – hybridized, P in PCl5 is sp3 d- hybridized whereas B in BCl3 is sp2 – hybridized.
Cis, trans and linkage isomers are shown by this complex.
CO ligand is bonded to the metal through σ and π bonding
Ni (CO)4 is tetrahedral, diamagnetic.
K4[Fe(CN)6] ionizes to give five ions giving maximum conductivity.
[Co(en)2 NO2Cl]Br shows linkage isomerism.
IUPAC name is potassium hexacyanoferrate (III).
C.N. = 6. O.N.=+3, No of d-electrons = 6, No. of unpaired d-electrons = 0
Complex having more rings in the structure will be more stable.
[Cr(NH3)6]3+ has three unpaired electrons.
[CoCl(NH3)3 (H2O)2]Cl2
From the complex ion [Ag(CN)2]‒ , Ag is not displaced by Cu.
Both optical and geometrical isomerisms are the types of streoisomerism.
A square planar complex is formed by hybridization of s, px, py and dx2-y2 − atomic orbitals of the metal.
[MA5 B] is not disubstituted complex and does not show geometric isomerism.
Ferrocene is [(C5H5)2] Fe].
[Cu(NH3)4]2+ is square planar in shape.
Cis platin, cis- [PtCl2(NH3)2 is used as an anticancer agent.
CO(NH3)5Cl3 is correctly written as [Co(NH3)5 Cl]Cl2 which on ionization gives 1+2 = 3 moles of ions out of which 2 moles of Cl- ions are present which react with 2 moles of AgNO3 to give 2 moles of AgCl(s) .
In K4[Ni(CN)4, the oxidation number of Ni is zero.
Brown ring complex obtained in NO−3 test is due to [Fe (H2O)5NO]2+.
As CN- is the strongest ligand, it will form the most stable complex.
Zeigler – Natta catalyst is TiCl4 + (C2H5)3Al.
trans complex is symmetrical and is optically inactive.
In Wilkinsons catalyst- (a homogeneous catalyst). (Ph3P)3RhCl, Rh is dsp2 hybridized giving a square planar shape to the compound.
