Assetion : In ` [Ni (en)_3 ]Cl_2 ` the Coordination number of ` Ni^(2+) ` is 6.
Reason : en is a bidentate ligand.

Statement-1: In [Co(en)_(3)]Cl_(3) , the coordination number of Co^(3+) ion is 3. Statement-2: 'en' is a bidentate ligand.

Coordination number of Ni in [Ni(C_2O_4)_3]^(4-) is

Coordination number of Ni in [Ni(C_2O_4)_3]^(4-) is:

Coordination number of Ni in [Ni(C_2O_4)_3]^(4-) is:

Find the oxidation number of Ni [Ni(CN)_3 Cl]^(2-)

Assertion : The [Ni(en)_3]Cl_2 (en = ethylenediamine) has lower stability than [Ni(NH_3)_6]Cl_2 . Reason : In [Ni(en)_3]Cl_2 the geometry of Ni is trigonal bipyramidal.
