1.	The coordination number of nickel (II) ion is 4. NiCl_(2)+underset(("excess"))(KCN)tounderset(("cyano complex"))(X) X+underset(("excess"))(conc. HCl)tounderset(("chloro complex"))(Y) The IUPAC names for the complexes X and Y are respectively.
Answer» potassium tetracyanidonickle (II) , potassium tetrachloridonickle (II) tetracyanidonickel(II), tetracyanidonickel(II) tetracyanido potassium nickelate(II), tetrachlorideo potassium nickelate(III) potassium tetracyanidoickelate(II), potassium tetrachloridonickelate (II). SOLUTION :`NiCl_(2)+underset(("excess"))(4KCN)tounderset("potassium tetra cyanidonickelate"(II))underset(X)(K_(2)[Ni(CN)_(4)])+2KCL` `K_(2)[Ni(CN)_(4)]+4HCl to underset("potassium tetrachloridonickelate"(II)) (K_(2)[Ni(Cl)_(4)])+4HCN`
