This document provides study material and homework questions for an undergraduate organic chemistry course. The homework asks students to compare the stability of various carbanion intermediates and explain their reasoning. Students are asked to consider factors like inductive effects, resonance stabilization, and ring stability in determining which species in several pairs of carbanions would be more stable.
