Consider the hydrolysis of . Which of the following statements is true regarding the products formed?

  1. A.The products are and , both of which are non-reducing sugars.
  2. B.The hydrolysis results in an equimolar mixture of and , known as invert sugar.
  3. C.The reaction involves the cleavage of a linkage.
  4. D.The resulting mixture is dextrorotatory because has a higher specific rotation than .
Show correct answer & step-by-step solution

Correct answer: BThe hydrolysis results in an equimolar mixture of and , known as invert sugar.

Solution

  1. is a disaccharide composed of and linked by an glycosidic bond.
  2. Hydrolysis of yields and .
  3. This mixture is called invert sugar because the sign of optical rotation changes from dextrorotatory to levorotatory.
  4. Hence the answer is (B).
