Vedclass · Answer

(C) ligand is an ion or molecule that binds to a central metal atom or ion to form a coordination complex. This requires the ligand to have at least one lone pair of electrons to donate to the metal center. $PH_3$ has a lone pair on $P$. $NO^{+}$ is a nitrosonium ion,which acts as a ligand in many complexes. $Cl^{-}$ is a classic anionic ligand. $BF_3$ is an electron-deficient molecule (Lewis acid) with an incomplete octet on the boron atom. It does not have a lone pair to donate to a metal center,so it is not considered a ligand.
