Vedclass · Answer

(D) In metal carbonyls and metal phosphine complexes,both $CO$ and $PF_3$ act as $\sigma$-donors and $\pi$-acceptors.$CO$ accepts electron density from the metal into its empty antibonding $\pi^*$ molecular orbital.$PF_3$ accepts electron density from the metal into its empty $3d$ orbitals (or $\sigma^*$ orbitals depending on the model).Option $A$ is incorrect because $CO$ is not a $\pi$-donor.Option $B$ is incorrect as both can be toxic.Option $C$ is a physical property difference,but the primary chemical distinction in coordination chemistry is the nature of the $\pi$-acceptor orbital.Option $D$ correctly identifies the difference in the acceptor orbitals involved in back-bonding.

Which are the dissimilarities between $CO$ and $PF_3$?
