Question

In the manufacture of iron, a gas (A) is formed in the zone of combustion of the blast furnace. The gas (A) reacted with coke in the zone of fusion to form another gas (B). X moles of (B) reacts with iron at ${200}^o$C and 100 atm pressure to form a compound (C).

The d orbital(s) involved in the formation of the complex (C) will be :

• A. $d_{z^2}$
• B. $d_{x^2-y^2}$ and $d_{z^2}$
• C. $dxy$ and $d_{x^2-y^2}$
• D. $d_{x^2-y^2}$

Answer 1

The correct option is A $d_{z^2}$

$Fe(CO{)}_5$
hybridization = $ds{p}^3$
d-orbital = $d_{z^2}$ Geometry = Trigonal bipyramidal
