B Which statement BEST describes the distinction between a hydration and a dehydration reaction? a) Hydration requires a carbonyl group, and dehydration does not. b) Hydration is the addition of water, and dehydration is the loss of water. c) Hydration results in breaking bonds, and dehydration creates bonds. d) Hydration is an oxidation, and dehydration is a reduction. e) Hydration and dehydration actually describe the same process.

1. Esters can be formed by the condensation of a carboxylic acid with the hydroxyl group of an alcohol or phenol. a) Use structures to show the condensation of acetic acid (IUPAC: ethanoic acid) with the hydroxyl of cyclohexanol. b) Explain why 'condensation' is an appropriate name for this reaction. c) You'll synthesize the ester in aspirin by condensing the phenol group of salicylic acid not with acetic acid, but with acetic anhydride. Explain why the experiment calls for the use of an anhydride, rather than an acid.
