- Explain the following observations: (i) The enthalpies of atomisation of transition metals are quite high. (ii) There is a close similarity in physical and chemical properties of the 4d and 5d series of the transition elements, much more than expected on the basis of usual family relationship. (iii) The members in the actinoid series exhibit larger number of oxidation states than the corresponding members in the lanthanoid series.arrow_forwardThe absorption spectra of solutions containing Br2 are solvent dependent. When elemental bromine is dissolved in nonpolar solvents such as hexane, a single absorption band in the visible spectrum is observed near 500 nm. When Br2 is dissolved in methanol, however, this absorption band shifts and a new band is formed. Account for the appearance of the new band. Is the 500 nm band likely to shift to a longer or shorter wavelength in methanol? Why?arrow_forward(a) Calculate the number of unpaired electrons in the following gaseous state ions: Mn2+, Cr3+, V3+ and Fe2+ which one of these in the most stable in aqueous solutions? (At. nos.

(iii) The highest oxidation state of a transition metal is exhibited in its oxide or fluoride.arrow_forward
- The molecules Cr(CO)6 and MnCl(CO)5 are both octahedral in their molecular geometry. Are these two molecules discernable by their CO stretches using IR spectroscopy. Using group theory approach and the CO bond vectors as the basis, show that these molecules are (or are not) discernable by IR spectroscopy.arrow_forwardexplain what is meant by the statement, "the carbon-metal bonds of organolithium and organomagnesium compounds have appreciable carbanionic character"arrow_forward“Mango-globin” is a hemoglobin variant in which the iron atoms in each subunit have been substituted with manganese atoms. Mango-globin binds to oxygen at very high partial pressures, but does not exhibit any cooperativity. Propose an explanation for this observation. (Hint: the ionic radius of Fe2+ is 77 pm; the ionic radius of Mn2+ is 82 pm.) The free energy change for a chemical reaction is defined as follows: ∆?!= ∆? ̊!+ RT ln [products] / [reactants] When a reaction is at equilibrium, ∆G’ = 0, and this expression simplifies to: ∆? ̊!= −RT ln [products] / [reactants] At equilibrium, the ratio of product to reactant concentrations is nothing more than the equilibrium constant, Keq, for the reaction. Under these conditions: ∆G ̊’ = -RT ln Keqarrow_forward

Would NMR be enough in this case to make the determination?arrow_forwardIn CrBr2, which crystallizes with a distorted CdI2 structure, four Cr-Br distances are 254 pm and two are 300 pm.
