The number of geometrical isomers possible in triamminetrinitrocobalt ( III ) is X and in trioxalatochromate ( III ) is Y . Then the value of X + Y is _ _ _ _ .

Step-by-step solution

Triamminetrinitrocobalt ( III )   → Co NO 2 3 NH 3 3 trioxalatochromate ( III ) ion → Cr C 2 O 4 3 3 - Co NO 2 3 NH 3 3 Cr C 2 O 4 3 3 - X + Y = 2 + 0 = 2 . 0
