Quizplus · Accepted Answer

Butanoic acid can be prepared from the reaction of an alcohol with a carboxylic acid, known as the Fischer esterification. Choice C involves the reaction of an alcohol (OH) with carbon monoxide (CO) to form a carboxylic acid, butanoic acid. The other choices involve different reactions such as using sodium cyanide (NaCN) or magnesium bromide (MgBr) which are not typically used in the preparation of butanoic acid.
