3 the optical rotations for the a and anomers of d mannose are ad 293
Question
3. The optical rotations for the a- and ß-anomers of D-mannose are [a]D = +29.3° and [a]D =-17.0°, respectively. In water each form mutarotates to an equilibrium value of [a]D=+14.2°.
Calculate the percentage of each anomer present at equilibrium.
