Vedclass · Answer

(C) Acetylacetone $(acac)$ is $CH_3COCH_2COCH_3.$ Upon deprotonation,it forms the acetylacetonate anion,$CH_3COCHCOCH_3^-.$ When this anion coordinates with $Co^{3+},$ the metal ion binds to the two oxygen atoms. This creates a ring consisting of the metal atom,two oxygen atoms,and three carbon atoms from the ligand backbone. Counting these atoms $(Co, O, C, C, C, O)$,we find that the chelate ring is a six-membered ring.

The anion of acetylacetone $(acac)$ forms $Co(acac)_3$ chelate with $Co^{3+}.$ The rings of the chelate are
