Question

Glucose when treated with `CH_3 OH` in the presence of dry HCl gives `alpha` and `beta`-methylglucosides because it contains
A. An aldehydic group
B. a `CH_(2)OH` group
C. a ring structure
D. five -OH groups.

Answer 1

Correct Answer - A
In the structure of glucose the `C_(1)` carbon is chiral in hemiacetal form and exists in two stereoisomeric forms `alpha` and `beta` . These two of glucose give two methyl glycosides i.e., `alpha` and `beta`-methylglucosidic .
