Coordination Compounds

A) [Co(en)(NH3)3(H2O)]+3 complex is type of [M(AA)b3c] have two G.I
B) If (en) is replaced by two cynide ligand, complex will be type of [Ma3b2c] an dhave 3 G.I
C) [Co(en)(NH3)3(H2O)]3+ have d6 configuration (t2g6) on central metal with SFL therefore it is dimagnetic in nature.
D) Complex [Co(en)(NH3)3(H2O)]3+ have lesser CFSE ( O) value than [Co(en)(NH3)4]3+ therefore complex [Co(en)(NH3)3(H2O)]+ absorbs longer wavelength for d–d transition
