What is the specific rotation of an equilibrium mixture of fructose? (Hint : The specific rotation of an equilibrium mixture of glucose is +52.7.)
ANSWER:
Solution 27PKetose can also exist in the solution predominantly in the cyclic forms. For example, D-fructose forms a five-membered-ring hemiacetal as a result of the reaction of the reaction of its C-5 OH group with its ketone carbonyl group. Here the -OH group is bonded to the new asymmetric center which is trans to the pr
