1.In aqueous solutions there are three forms of glucose: the α-form (36%), the β-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 β-form is more abundant than the α-form.

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
