The coordination number of `Ni^(2+)` is 4
`NiCI_(2) + KCN` (excess)rarr`A` (cyano complex)
`NiCI_(2)+conc.HCI` (excess) rarr `B` (Chloro complex)
The `IUPAC` name of `A` and `B` are .

A

potassium tetracyanonickelate(II),potassium tetrachloronickelate(II) .

B

tetracyanopotassiumnickelate(II)tetrrachloropotassiumnickelate(II) .

C

tetracyanonickel(II) tetrachloronickel(II)

D

potassium tetracyanonickel(II),tetracholoronickel(II) .

Text Solution

Verified by Experts

The correct Answer is:
a
`NiCI_(2)+4KCNrarrK_(2)[Ni(CN)_(4]+2KCI`
`A is K_(2)[Ni(CN)_(4)]`
Potassium tetracyanonickelate(II)
`K_(2)[Ni(CN)_(4)]+4HCI(conc)rarr,K_(2)[Ni(CN)_(4)]+4HCN`
`B is K_(2)[NiCI_(4)]`
Potassium tetrachloridonickelate(II) .
