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.

Text Solution

Verified by Experts

`{:(,alpha-D glucose,hArr,beta-D glucose),("At equilibrium",36.4,,63.6):}`
`K_(c )=63.6//36.4=1.747`
