Question

Enumerate the reaction of D-glucose which cannot be explained by the open chain structure

Answer 1

Enumerate the reactions of D-glucose which cannot be explained by its open chain structure. (1) Aldehydes give 2, 4-DNP test, Schiff's test, and react with NaHSO4to form the hydrogen sulphite addition product. ... (2) The pentaacetate of glucose does notreact with hydroxylamine.
hope u got ur answer..
pls mark it as brainliest.

Answer 2

Hey !!

The penta-acetate of glucose does not react with hydroxyl amine indicating the absence of free CHO group.

(OR)

Glucose give the characteristic reaction of alcohols and carbonyl group (aldehydes and ketones). However it does not form addition compound with ammonia and sodium bisulphite and does not respond to 2,4 - DNP test and Schiffs test.

GOOD LUCK !!
