Discuss the structure of [Cu (NH_3)_4]^2+ on the basis of VBT.

Discuss the struchure of [Co(NH_3)_6]^(3+) ion on the basis of valence bond theory. Whether it is an inner orbital or outer orbital complex ion ?

How is XeO_(3) prepared from xenon fluorides ? Describe the structure of XeO_(3) on the basis of hybridisation.

PtCl_(4)andNH_(3) may form five complexes, A (PtCl_(4)*6NH_(3)),B(PtCl_(4)*5NH_(3)),C(PtCl_(4)*4NH_(3)),D(PtCl_(4)*3NH_(3))andE(PtCl_(4)*2NH_(3)) . One mole of each A, B, C, D and E reacts with excess of AgNO_(3) to yield 4, 3, 2 and 1 mole(s) of AgCl respectively, while E gives, no AgCl. The conductance of their solutions are in the order AgtBgtCgtDgtE . On the basis of Werner's theory, write their strucutre and give the total number of ions given by one complex.
