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. Deduce the empirical formula of the ester. ..........................................................................................................................................
