1.	Draw the figure to show the splitting of d-orbitals in an octahedral crystal field. How does the magnitude of Delta_(0) decide the actual configuration of d-orbitals in a coordination entity? (i) Write IUPAC Name of the complen [Co(en)_(3)]^(3+) (ii) Draw all the isomers (geometrical and optical) of (a) [PtCl_(2)(en)_(2)]^(2+) (b) [CrCl_(2)(o x)_(2)]^(3-)
Answer» Solution :If `Delta_(0) lt P`, the fourth electron enters one of the eg ORBITALS giving the configuration `t_(2g)^(2)eg^(1)`. (High spin complex) If `Delta_(0) gt P`, the fourth electron enters `t_(2g)` orbital with configuration `t_(2g)^(4)eg^(0)`. (LOW spin complex) trisethylenediamminecoblat (III) ion.
