The correct statement(s) regarding the binary transition metal carbony...
(a) Electronic configuration of central metal atom in both cases is [Ar] 3d104s24p6 (8 electrons in
outermost shell and 18 valence electrons respectively).
(b) Low spin complex because CO is a strong field ligand.
(c) Metal-carbon bond strengthens when the oxidation state of metal is lowered.
(d) The carbonyl C – O bond becomes stronger when the oxidation state is increased.
