In aqueous solutions there are three forms of glucose: the D-form (36%), the E-form (64%)
and a trace amount of the open-chain form. At equilibrium, the alpha and beta cyclic forms are
interconverted by way of the open chain structure. Explain (a) why the cyclic forms exist
predominately in solutions, and (b) why the E-form is more abundant than the D-form.

The bond energy for the van der waals bond between two helium atoms is 7.9×10−4ev. assuming that the average kinetic energy of a helium atom is (3/2)kbt, at what temperature is the average kinetic energy equal to the bond energy between two helium atoms
