In metal carbonyls, $d_{C-O}$ is more as compared to that in $CO$ molecule

Vedclass · Answer

(A, B) In metal carbonyls, the back-bonding from metal to $CO$ increases the bond order of $M-C$ and decreases the bond order of $C-O$, resulting in a longer $C-O$ bond length $(d_{C-O})$ compared to free $CO$. Thus, statement $A$ is $TRUE$.Statement $B$ is $TRUE$ because these complexes differ in the number of water molecules coordinated to the metal ion versus those present as lattice water.Statement $C$ is $FALSE$ because $dsp^2$ hybridisation involves $d_{x^2-y^2}$ orbital, not $d_{z^2}$.Statement $D$ is $FALSE$ because facial and meridional isomers are generally optically inactive due to the presence of planes of symmetry.
