Introduction to functional groups: a group of atoms within a molecule that has a characteristic chemical behaviour. Polar bonds Formal charge Resonance McMurry Chapter 2 (part 2) Acids and bases Brønsted acids and bases Lewis acids and bases Acid - Base Reactions Brønsted definition: an acid is a proton donor; a base is a proton acceptor. In the reverse direction, water is the proton donor and acetate is the proton acceptor. E.g.: O C CH 3 OH O C O 3 (-) + OH(-) + H 2 O acetic acid acetate acid base conjugate acid conjugate base In the forward direction, acetic acid is the donor and hydroxide is the acceptor.
