The specific rotation of the pure a-anomer of a monosaccharide is +169.7 and that of the pure b-anomer is +29.4.A solution of the pure a-anomer produces a specific rotation of +61.4.Based on this data,which of the following is correct?
A) The solution contains more of the a-anomer.
B) The solution is an equimolar mixture of the two anomers.
C) A solution of the pure b-anomer would produce the same specific rotation.
D) The change in specific rotation is due to the irreversible formation of the open-chain monosaccharide.
E) All of these.
