Short Answer TypeOn the basis of crystal field theory, write the electronic configuration for d4 ion if ∆o < P ?
On the basis of crystal field theory, for a d4 ion, if ∆o< P, then the complex is a high spin complex formed by the association of weak field ligands with the metal ion. As a result, the fourth electron enters one of the eg orbitals, thereby, exhibiting the electronic configuration t2g3 eg1.
Write the hybridization and magnetic behaviour of the complex [Ni(CO)4].
(At.no. of Ni = 28)
Calculate emf of the following cell at 25 °C:
Fe | Fe2+(0.001 M) || H+ (0.01 M) | H2 (g) (1 bar) | Pt(s)
E°(Fe2+ | Fe) = –0.44 V E°(H+ | H2 ) = 0.00 V
Give reasons for the following observations:
Lyophilic sol is more stable than a lyophobic sol.
Give reasons for the following observations:
It is necessary to remove CO when ammonia is prepared by Haber's process.
3.9 g of benzoic acid dissolved in 49 g of benzene shows a depression in freezing point of 1.62 K. Calculate the van't Hoff factor and predict the nature of solute (associated or dissociated).
(Given: Molar mass of benzoic acid = 122 g mol-1, Kf for benzene = 4.9 K kg mol-1
