Acid-Base reactions are central in Organic Chemistry for understanding important topics such as SN2 and SN1 nucleophilic substitution reactions, elimination reactions, resonance stabilization and general trends of reactivities. In this cheat sheet study guide, you will find the key concepts of acids and bases and acid-base reactions. It summarizes the factors such as electronegativity, polarizability, induction, and resonance-stabilization for determining the acidity of molecules and understating the pKa values and relationship to acid strength. The principle of determining the acid-base equilibrium and main implication of Henderson–Hasselbalch equation are also addressed with specific examples.
