MCQ
What is incorrect about homoleptic metal carbonyls ?
  • A
    $M -C$, $\sigma -$ bond is formed by donation of lone pair of electrons from $CO$
  • B
    $M -C$, $\pi -$ bond is formed by back donation of electron from filled $d-$ orbital of metal to vacant $p-$ orbital of carbon
  • ✓
    $M -CO$ bonding produce synergic effect
  • D
    Metal carbonyl contain only $\sigma-$ bonds
✓

Answer

Correct option: C.
$M -CO$ bonding produce synergic effect
c
