Short Answer TypeWhat do you understand by crystal field splitting? Draw figure to show splitting of degenerate d-orbitals in an octahedral crystal field.
What are the main postulates of Werner’s theory? Write the correct formula and IUPAC name of the coordination compound for CrCl3.6H2O, one mole of which give two moles of AgCl with AgNO3,.
What is complex? How is it different from a double salt?
Double salts as well as complexes are formed by the combination of two or more stable compounds in stoichiometric ratio. However, they differ in the fact that double salts such as carnallite, KCl.MgCl2.6H2O,
Mohr’s salt, FeSO4.(NH4)2SO4.6H2O, potash alum, KAl(SO4)2.12H2O, et,.dissociate into simple ions completely when dissolved in water. However, complex ions such as [Fe(CN)6]4– of K4Fe(CN)6, do not dissociate into .
