Which of the following statement is correct with respect to the metal carbonyls of Ist  transition series?
  • a)
    As M—Cπ bonding increases, the C–O bond becomes weaker.
  • b)
    As positive charge on the central metal atom increases, the C – O bond becomes weaker.
  • c)
    As electron density on the central metal atom increases, the C – O bond becomes weaker.
  • d)
    (A) and (C) both.
Correct answer is option 'D'. Can you explain this answer?

Which of the following statement is correct with respect to the metal ...
Order of C–O bond strength; [Mn(CO)6]+ > [Cr(CO)6] > [V(CO)6]- > [Ti(CO)6]2- and [Ni(CO)4] > [Co(CO)4]- > [Fe(CO)4]2-
(A) True statement.
(B) As + ve charge on the central metal atom increases, the less readily the metal can donate electron density into
the π* orbitals of CO ligand to weaken the C–O bond.
(C) In the carbonylate anions, the metal has a greater electron density to be dispersed, with the result that M–Cπ
bonding is enhanced and the C–O bond is diminished in strength.
