In the context of proper depiction of chemical reaction mechanisms:
Intended outcome: 1. Identify nucleophiles/electrophiles, 2. label nucleophilic electron pairs, 3 flow of arrows.
1 – Create a list of reagents. Simplify non-participating atoms, highlight functional groups, lead students to notice and identify nucleophilic and electrophilic sites.
2 – Provide some near-complete mechanisms missing electron pairs. Have students label electron pairs properly.
3 – Provide reagents, intermediates, and products. Have students complete the electron flow arrows.
Assess according to proper identification.
