In the manufacture of iron 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)` will be
The magnetic moment and effective atomic number of the `C` repectively, are
(a) `4.93` and `36`
(b) `0` and `34`
(c ) ``0` and `36`
(d) None .

Answer

A

Explanation

`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 .
