The chemical changes associated with endothermic and exothermic peaks in differential scanning calorimetry and differential thermal analysis are to be listed. Concept introduction: Determination properties of materials are done on the basis of change of temperature and it is known as thermal analysis. Many methods are there as example DSC or DTA etc.

Question

Consider the reaction of a propanoate ester with hydroxide ion shown below. A series of four alcohol leaving groups were tested to determine which would be the best leaving group. Based on the pKa values of the alcohols, predict which alcohol would produce the fastest hydrolysis reaction. HO FOR A Alcohol I, pKa =16.0 B Alcohol II, pKa =10.0 C Alcohol III, pKa = 7.2 + ROH D Alcohol IV, pKa = 6.6
