`alpha`-glucose is oxidized by `HIO_(4)` more rapidly than its `beta`-anomer at the 1-2 bond.

Answer» `alpha`-glucopyranose is cis-1, 2-diol and the B-anomer is the trans 1, 2 diol. Since the former can form a cyclic ester with periodic acid and latter can not, the former is oxidised more rapidly than the latter.
