Iron carbonyl, Fe(CO)_5 is - Vidyadip

MCQ

Iron carbonyl, $Fe(CO)_5$ is

A
tetranuclear
B
mononuclear
C
trinuclear
D
dinuclear

✓

Answer

$\mathrm{Fe}(\mathrm{CO})_{5}$

$\mathrm{EAN}=\mathrm{Z}-\mathrm{O} \cdot \mathrm{N} \cdot+2(\mathrm{C} \cdot \mathrm{N} \cdot)$

$=26-0+2(5)$

$=26+10$

$=36$

only one central metal atom/lon is present and it follows $EAN$ rule, so it is mononuclear
