Two compounds A and B isolated from plants have the following chemical data. Determine the their structures from the data provided (and give the structures of their derivative C)

b) Disaccharide E is a reducing sugar. It is hydrolyzed by an α-glycosidase enzyme, which means it contains an α- glycoside link. Treatment of E with Ag2O and excess Mel gives an octamethyl derivative F. Hydrolysis of F in dilute aqueous acid gives the pair of molecules shown below. Write the structures of E and F. (If the stereochemistry at a particular carbon is not determined by the above data, indicate this with a wavy line as shown below.) HO OMe OMe Is is MeO MeO MOH OMe mOH OMe OMe

Give detailed Solution with explanation needed with structure. don't give Handwritten answer

Some of the following compounds show aromatic properties, and others do not. Predict which ones are likely to be aromatic, and explain why they are aromatic or not. a) b)
