Ques. 1AIPMT 2001

Which of the following organometallic compounds is and bonded?

  1. [Fe( 5-C5H5)2]
  2. K[PtCl3( 2-C2H4)]
  3. [Co(CO)5NH3]2+
  4. Fe(CH3)3

Answer

(3) [Co(CO)5NH3]2+

Solution

As per NCERT, the metal–carbon bond in metal carbonyls possesses both and character.

CO donates its lone pair on carbon into a vacant metal orbital M–C bond.

A filled metal d orbital donates electrons back into the vacant antibonding * orbital of CO M–C bond (synergic bonding).

The metal carbonyl [Co(CO)5NH3]2+ is the and bonded organometallic compound.

Fe(CH3)3 has only M–C bonds.
