Vedclass · Answer

(C) donor site is an atom that can donate a lone pair of electrons to the central metal ion to form a coordinate bond. $1$. Triethylene tetramine $(trien)$ has $4$ nitrogen donor atoms (tetradentate). $2$. Ethylenediamine tetracetate ion $(EDTA^{4-})$ has $6$ donor atoms ($4$ oxygen and $2$ nitrogen) (hexadentate). $3$. Ethylenediamine triacetate ion $(EDTA^{3-})$ has $5$ donor atoms ($3$ oxygen and $2$ nitrogen) (pentadentate). $4$. Diethylene triamine $(dien)$ has $3$ nitrogen donor atoms (tridentate). Therefore,the correct answer is Ethylenediamine triacetate ion.
