Electron counting exercise motivated by a recent paper (J. Am. Chem. Soc. 2015, 137, 12808-12814 doi: 10.1021/jacs.5b08406) featuring a proton switchable ligand.

Students will be able to:
- assign charges at ligation points in the ionic formalism (L/X classification in the CBC formalism) to count electrons and assign oxidation states (valence numbers).
- describe how tautomerization in proton-responsive ligands affects bonding and electron count.
None.
This exercise has not been implemented yet. We have provided materials for students and faculty in both the ionic and CBC formalisms. The ChemDraw file used to create all images is also attached in case you want to edit any of the images we provide.
Evaluation
You could choose other compounds from the Szymczak paper, such as the H2 activated species (5) to test the students’ ability to apply this new knowledge.
This activity has not yet been implemented or assessed.
