Packet 11: Bonus 12
The Davies-Green-Mingos rules predict the regiochemistry of nucleophilic addition to these compounds. For 10 points each,
[10m] Name these compounds which bind to a metal center in coordination complexes.
ANSWER: ligands
[10e] Chemists often consider the denticity of ligands, or how many atoms in a ligand coordinate to the metal center. This number, the denticity of EDTA, also happens to be the atomic number of carbon.
ANSWER: six
[10h] This word names an effect in which ligands especially in square planar complexes are more labile towards ligand substitution. This word names the E isomer of an alkene.
ANSWER: trans [or trans effect]
