QJEEM04Ch579f: JEE Main 2004 Chemistry - Class 12 JEEM04Ch579f Solution: The coordination number of central metal atom in a complex is…

The coordination number of central metal atom in a complex is determined by :

Multiple Choice Options

  • A the number of ligands around a metal ion bonded by sigma bonds
  • B the number of only anionic ligands bonded to the metal ion
  • C the number of ligands around a metal ion bonded by sigma and pi- bonds both
  • D the number of ligands around a metal ion bonded by pi-bonds

Step-by-Step Verified Solution

The coordination number of central metal atom in a complex is equal to number of monovalent ligands, twice the number of bidentate ligands and so on, around the metal ion bonded by coordinate bonds. Hence coordination number == no. of σ\sigma bonds formed by metals with ligands
