Long Answer TypeWrite the correct formulae for the following coordination compounds:
(a) CrCl3.6H2O (violet, with 3 chloride ions/unit formula)
(b) CrCl3.6H2O (light green, with 2 chloride ion/unit formula)
(c) CrCl3.5H2O (dark green, with 1 chloride ion/unit formula)
Short Answer TypeA coordination compound has the formula CoCl3.4NH3. It does not liberate ammonia but forms a precipitate with AgNO3. Write the structure and IUPAC name of the complex compound.
Long Answer TypeDraw the structure of the following compounds:
(a) cis-[CrCl2(OX)2]3– (b) [Ni(CN)4]2–
(c) [Fe(CN)6]3– (d) Meridional [CrCl3(NH3)3]+
(e) trans-[PtCl2(en)2]2+.
Short Answer TypeWrite down the IUPAC name of the following complex:
[Cr(NH3)2Cl2(en)]Cl (en = ethylenediamine)
On the basis of crystal field theory, write the electronic configuration for d4 ion if ∆o < P ?
Write the hybridization and magnetic behaviour of the complex [Ni(CO)4].
(At.no. of Ni = 28)
Carbonyl, CO being a strong field ligand causes the pairing of up valence electrons in the Ni atom against the Hund's Rule of Maximum Multiplicity. This results in the formation of an inner orbital complex, [Ni(CO)4] having diamagnetic character. [Ni(CO)4] has sp3 hybridization.
Which of the following is a more stable complex and why?
(i) [Co(NH3)6]3+
(ii) [Co(en)3]3+
