MCQ
Iron carbonyl, $Fe(CO)_5$ is
- Atetranuclear
- Bmononuclear
- Ctrinuclear
- Ddinuclear
✓
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
