Write IUPAC name for each of the following and indicate oxidation state, electronic configuration and coordination number. Also give stereochemistry, magnetic moment :
`[Co(NH_(3))_(5)Cl]Cl_(2)`

Explanation

IUPAC name : pentaamminechloridocobalt (III) chloride
Coordination number of `Co=5+1=6`
Stereochemistry = octahedral, oxidation state of `Co=+3`
Electronic configuration. Of `Co^(2+)=3d^(6)=t_(2)^(6)e_(g)^(0)`
(`because NH_(3)` is a strong - field ligand)
No. of unpaired electrons = 0 , Magnetic moment `(mu)=0`
