alpha-glucose is oxidized by HIO(4) more...

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

Text Solution

Verified by Experts

The correct Answer is:
`alpha-"glucose" underset("oxidation fast")overset(HlO_(4))(rarr)5HCOOH +HCHO ; beta-"glucose" underset("oxidation slow") overset(HlO_(4))(rarr) 5HCOOH+HCHO`
Reason : `(##RES_ORG_CHM_V02_XII_C04_E01_256_A01##)`
cis-1,2-diol can form a cyclic ester with `HIO_(4)` so it is oxidized more rapidly than latter.
`(##RES_ORG_CHM_V02_XII_C04_E01_256_A02##)` trans-1,2-diol can't form a cyclic ester intially. First the ring opens then only it can undergo oxidation.
