The Specific Rotation of the Pure A-Anomer of a Monosaccharide

question 25

Multiple Choice

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.
