MCQ
The value of X in Fe(CO)2(NO)x, is:
- A3
- B4
- C2
- D1
✓
Answer
- 2
Explanation:
The coordination sphere of a coordination compound or complex consists of the central metal atom/ion plus its attached ligands. The coordination sphere is usually enclosed in brackets when written in a formula. The coordination number is the number of donor atoms bonded to the central metal atom/ion.
Most metal complexes or compounds except for alloys. Specific examples include hemoglobin and Ru3(CO)12.
So the total electron should be 18
valence electron of iron is = 8
CO gives = 2e−, NO gives 3e−
18 = 8 + (2 × 2) + (3 × x)
18 - 8 - 4 = 3x
x = 2
