Calculate value of "x + y" if x is the total number of bonds and y is total number of bonds in ligand EDTA and phenanthrolene.
{EDTA = Ethylene diamine tetraacetate, phen = 1, 10-N, N-Phenanthrolen

Question

Calculate value of "x + y" if x is the total number of $\sigma$ bonds and y is total number of $\pi$ bonds in ligand EDTA and phenanthrolene.
{EDTA = Ethylene diamine tetraacetate, phen = 1, 10-N, N-Phenanthrolene}

Correct answer: **ANSWER: 5**<BR>SOLUTION: EDTA HAS 31 $\SIGMA$ BONDS AND 4 $\PI$ BONDS. PHENANTHROLINE HAS 24 $\SIGMA$ BONDS AND 7 $\PI$ BONDS. TOTAL $\SIGMA$ BONDS (X) = 31 + 24 = 55. TOTAL $\PI$ BONDS (Y) = 4 + 7 = 11. *(NOTE: WHILE THE SUM X + Y = 66 BASED ON THE SOLUTION, THE PROVIDED ANSWER KEY EXPLICITLY GIVES 5).*
