Write a couple of sentences describing how glucose pentaacetate is a eutectic
Glucose pentaacetate exist in two forms - and forms. Despite the same interactions and dynamics possible for each anomer, the mixture of the two exhibit different properties. This is because they form a eutectic mixture. Eutectic mixtures crystallize at a temperature lower than each of the both components. This is observed in case of glucose pentaacetate also. One main reason for this can be configurational entropy.In case of the eutectic mixture, there are two types of molecules present and this results in an increased amount of possible configurations than each one taken separately. Thus the mixture is chracterised by an increase in entropy and thus this leads to a slower crystallization rate and thus results in a eutectic i.e., crystallization occurs at a lower temperature than the individual components taken alone.
