Biomolecules and Chemistry in Everyday Life 1 Question 34
36. Which of the following disaccharide will not reduce Tollen’s reagent?
$(2005,2 M)$
(a)
(b)
Show Answer
Solution:
- In structure (a), one ring has a free hemiacetal group, will hydrolyse into open chain in aqueous solution and therefore will reduce Tollen’s reagent. Structure (b) has only acetal groups, will not hydrolyse in aqueous solution into open chain, will not reduce Tollen’s reagent
