A carboxylic acid reacts with an alcohol to produce an ester and water. Under certain conditions, this reaction can be reversed so an ester reacts with water to produce a carboxylic acid $$\(\mathbf{X}\)$$ and an alcohol $$\(\mathbf{Y}\)$$. The reaction reaches an equilibrium. The forward reaction is endothermic. Name carboxylic acid $$\(\mathbf{X}\)$$ and draw its displayed formula. name ...................................................................................................................................... displayed formula
