Find the theoretical yield of the coordination compound. Acetylacetone (CH 3 COC

Question

Find the theoretical yield of the coordination compound.

Acetylacetone (CH3COCH2COCH3, acac) is the ligand to cobalt (III)

CH3COCH2COCH3 <--> H+ + CH3COCHCOCH3-

in this synthesis, 1.344g of Cobalt(II) was weighed out and 15mL of acetylaceton was added to it. additionally 30 mL of 10% H2O2 was added to the solution. product was filtered then added to 50mL of heptane then filtered again and allowed to dry.

what would be the theoritical yield of Co(acac)3 (cobalt(III) acetylacetonate complex)?

Explanation / Answer

This is a 1:1 relationship between the product and the reactant so:

MM of Co = 58.93 g/mol

MM of acac = 100.13 g/mol

moles of Co = 1.344 / 58.93 = 0.0228 moles

This would be the moles of the final product so:

MM of Co(acac)3 = 356.26 g/mol

m = 0.0228 * 356.26 = 8.1227 g

Hope this helps
