4. Some Compounds are given below CH3COOH, CH3COOCH2CH3, CH3CH2OH 2x3 = 6
a) Identify which of the above given compounds is an ester. Write its name.
b) Write the equation of reaction of preparation of the ester.

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.
