Question 1

Mutarotation

Answer 1

spontaneous change in optical rotation observed when a pure anymore of a sugar is dissolved in water and equilibrates to an equilibrium mixture of anomie’s.

Question 2

When dissolved in water this anomer exhibits mutarotation. Indicate what is observed and why.

Answer 2

Observe change in optical rotation. Ring opening/closure → to equilibrium mixture of anomie’s.
