Assertion : The magnitude of charge density for a given ligand increases as the charge on the metal
ion increases.
Reason : is a weak field ligand towards but acts as a strong field ligand towards
Assertion : Bis(dimethylglyoximato)nickel(II) can show geometrical isomerism.
Reason : Tetrahedral complexes with chiral structure exhibit optical isomerism.
Assertion : tris (ethane-1, 2-diamine) nickel(II) chloride is homoleptic outer orbital complex
Reason : The geometry of Ni in tris (ethane-1, 2-diamine) nickel(II) chloride is trigonal bipyramidal.
Assertion : In complex the 'spin only' magnetic moment is close to 1.73 B.M.
Reason : All known mononuclear complexes of chromium (III), irrespective of the strength of the
ligand field, must have three unpaired electrons.
