Under acidic conditions, this reaction is known as a Fischer esterification. The first step of Fischer esterification is protonation of the carbonyl oxygen, followed by nucleophilic attack of the electrophilic carbonyl carbon by the alcohol. Next, a proton is transferred from the alcohol oxygen to the hydroxyl group of the carboxylic acid, resulting in the formation of water (a good leaving group). Finally, the carbonyl oxygen is deprotonated to yield an ester. For esters, the alkyl group (from the alcohol) is named first as the substituent prefix, followed by the carboxylic acid. The suffix -ic acid is then replaced by -ate. Therefore, the reaction of butanoic acid and ethanol by a Fischer esterification yields ethyl butanoate. (Choice A) Butyl ethanoate is an ester made from ethanoic acid and butanol. (Choices C and D) The reaction forms an ester rather than an anhydride. Anhydrides are made most commonly from a carboxylic acid and an acid chloride, and are named by stating the two carboxylic acids alphabetically and replacing acid with anhydride; butanoic ethanoic anhydride and acetic butanoic anhydride refer to the same compound because "acetic" is the common term for "ethanoic." Educational objective: Esters are carboxylic acid derivatives and may be formed by the condensation of a carboxylic acid and an alcohol under acidic conditions (Fischer esterification). Esters are named by using the alkyl group from the alcohol as a substituent prefix and the carboxylic acid as the root name, with the -ic acid suffix replaced by -ate.
