Metal carbonyls can have formula $M(C O)_x$, where $x=$ number of CO units coordinated to metal $M$. What is the formula of the carbonyl of Fo (26) if EAN of Fe in metal carbonyl is 36 ?

  • A
    $2$
  • B
    $3$
  • C
    $4$
  • Correct answer
    D
    $5$

Solution

EAN $=Z-(\mathrm{O} . \mathrm{N})+.2 x$ or $36=26-0+2 x$ or $x=5$

Hence, the correct answer is option: 'D'.
