NiCl 2+4 KCN arrow K 2[ Ni ( CN )4]+2 KCl , IUPAC name is Potassium tetracyanonickelate (II) NiCl 2+2 KCl + conc HCl arrow K 2[ Ni ( Cl )4], IUPAC name is Potassium tetrachloronickelate (II)

Q. The coordination number of $N i^{2 +}$ is $4$ .
$N i C l_{2} + K CN$ (excess) $\to A$ (cyano complex)
$N i C l_{2} +$ conc. $H Cl$ (excess) $\to B$ (chloro complex)
The IUPAC names of $A$ and $B$ are

Potassium tetra cyano nickelate (II), potassium tetra chloro nickelate (II).

Tetra cyano potassium nickelate (II), tetera chloro potassium nickelate (II).

Tetra cyano nickel (II), tetra chloro nickel (II).

Potassium tetra cyano nickel (II), potassium tetra chloro nickel (II).

$N i C l_{2} + 4 K CN \to K_{2} [N i (CN)_{4}] + 2 K Cl$ ,
$I U P A C$ name is Potassium tetracyanonickelate (II)
$N i C l_{2} + 2 K Cl +$ conc $H Cl \to K_{2} [N i (Cl)_{4}]$ ,
$I U P A C$ name is Potassium tetrachloronickelate (II)

Q. The coordination number of Ni2+ is 4 . NiCl2​+KCN (excess) →A (cyano complex) NiCl2​+ conc. HCl (excess) →B (chloro complex) The IUPAC names of A and B are
