A disaccharide forms a silver mirror with Tollens reagent and is hydrolyzed by a When the disaccharide is treated with excess methyl iodide in the presence of (a reaction that converts all the OH groups to groups) and then hydrolyzed with water under acidic conditions, 2,3,4 tri-O-methylmannose and 2,3,4,6-tetra-O-methylgalactose are formed.
a. Draw the structure of the disaccharide.
b. What is the function of Ag2O?
