In the manufacture of ions a gas `(A)` is formed in the zone of combustion of the blast furnace The gad `(A)` formed in the zone of combustion of the blast furnace. The gas `(A)` reacted with coke in the zone of fusion to from another gas `(B).X` moles of `(B)` reacts with iron at `200^(@)C` and `100` atm pressure to form a compounds `(C)` The d orbital (s) involved in the formation of the complex `(C)` will be (a) `d_(z)2` (d) ``d_(xy)` and `d_(x)2-y2` (c) ``d_(x)2-y2` and `d_(z)2` (d) `d_(x)2-_(y)2` .

Answer» Correct Answer - A
`CO_(2)+Crarr2CO`
`underset((B))(5CO)+Feunderset(100atm)overset(200^(@)C)rarrFeunderset((C))((CO)_(5)`
Hybridisation of ` (C )` dsp^(3)`
d -orbital `dz^(2)`
Geometry =Trigonal bipyramid .
