When alpha-D glucose is dissolved in wat...

When `alpha-D` glucose is dissolved in water, it undergoes a partial converion to `beta-D` glucose to exhibit mutarotation. This conversion stops when `63.6%` of glucose is in `beta` form. Assuming that equilibrium has been attained, calculate `K_(c)` for mutarotation.

A

`1.252`

B

`1.747`

C

`2.623`

D

`1.521`

Text Solution

Verified by Experts

The correct Answer is:
B
`alpha-D-"glucose"hArrbeta-D-"glucose"`
`36.4 63.6`
`K_(C)=(63.6)/(36.4)=1.747`
