2 anomers
3 epimers
4 enantiomers.

324629 Optical rotation of a freshly prepared solution of \(\mathrm{\alpha}\)-D-glucopyranose is \(\mathrm{+111^{\circ}}\) while that of \(\mathrm{\beta}\) - D-glucopyranose is \(\mathrm{+19.2^{\circ}}\). In solution, an equilibrium mixture of these two anomers is \(\mathrm{52.5^{\circ}}\). The percentage of \(\mathrm{\alpha}\)-form in the equilibrium mixture is

1 \(\mathrm{36 \%}\)
2 \(\mathrm{64 \%}\)
3 \(\mathrm{52.5 \%}\)
4 \(\mathrm{19.2 \%}\)

324630 The beta and alpha glucose have different specific rotations. When either is dissolved in water, their rotation changes until the same fixed value results. This is called

1 Epimerisation
2 Racemisation
3 Anomerisation
4 Mutarotation
