When `alpha-D` glucose is dissolved in water it undergoes a partial conversion to `beta-D` glucose to exhibit mutarotation. This conversion stops when 66.6% of glucose is in `beta` from `K_(C)` for the mutarotation `alpha-D`-glucose `hArr beta - D-` glucose, is

Text Solution

Verified by Experts

The correct Answer is:
B

`{:("at Initial",100,0),("at Equilibrium",33.3,66.6):} K_(C ) = ([beta- D- "glucose"])/([alpha- D- "fructose"]) = (66.6)/(33.3) = 2`
