Hybridization and Acidity Hydrocarbons are the least acidic class of compounds. The greater the s character on C, the greater the acidity. Consider the conjugate bases: p K a = 50 p K a = 44 p K a = 25 25% s 33% s 50% s

Inductive Effects Inductive effects - charge (- or +) transmission through σ bonds in a chain of atoms. Electron withdrawal (release) by electronegative (electropositive) atoms causes atoms further away to be positively (negatively) charged.
