(a)
Interpretation:
The products obtained from the reaction of lactobionic acid and
Concept introduction:
The hydrolysis of the disaccharides is done in the presence of acid as a catalyst. The hydrolysis of the disaccharide is the breaking of the glycosidic linkage to give two monosaccharides units. Glycosidic linkage is an acetal linkage and acetal linkage hydrolysis takes place in the presence of an acidic solution.
(b)
Interpretation:
The products obtained from the reaction
Concept introduction:
The methylation of the hydroxyl group of sugars is an important reaction. The methylation of hydroxyl groups is done with the help of methylating agent, dimethyl sulfate in the presence of strong base sodium hydroxide.
(c)
Interpretation:
The products obtained from the reaction product of part (b) and
Concept introduction:
The hydrolysis of the disaccharides is done in the presence of acid as a catalyst. The hydrolysis of the disaccharide is the breaking of the glycosidic linkage to give two monosaccharides units. Glycosidic linkage is an acetal linkage and acetal linkage hydrolysis takes place in the presence of an acidic solution.

- A. B. b. Now consider the two bicyclic molecules A. and B. Note that A. is a dianion and B. is a neutral molecule. One of these molecules is a highly reactive compound first characterized in frozen noble gas matrices, that self-reacts rapidly at temperatures above liquid nitrogen temperature. The other compound was isolated at room temperature in the early 1960s, and is a stable ligand used in organometallic chemistry. Which molecule is the more stable molecule, and why?arrow_forwardWhere are the chiral centers in this molecule? Also is this compound meso yes or no?arrow_forwardPLEASE HELP! URGENT!arrow_forward
