Question 15 Why are the OH groups of carboxylic acids more acidic than alcohols? O inductive electron donating by the carbonyl oxygen O reduced hydrogen bonding capacity O carboxylic acids are not more acidic than alcohols. O resonance stabilization of the carboxylate ion O because they have lower pKa values.

18-4 Answer true or false. (a) The functional groups of a carboxylic acid are a carbonyl group bonded to a hydroxyl group. (b) The VSEPR model predicts bond angles of 180° about the carbonyl carbon of a carboxyl group. (c) The VSEPR model predicts bond angles of 109.5° about the oxygen of the OH group of a carboxyl group. (d) The carbonyl carbon of a carboxyl group can be a stereocenter, depending on its location within a molecule. (e) Carboxylic acids can be prepared by chromic acid oxidation of primary alcohols and of aldehydes. (f) The product of chromic acid oxidation of hexanoic acid is 1-hexanol.
