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 MeDgives an octamethyl derivative F. Hydrolysis of F indilute aqueous acid gives the pair of molecules shown below. Write the structures of E and F. (If thestereochemistry at a particular carbon is not determined by the above data, indicate this with a wavy line asshown below.)HO OMeOMeMeOMeOOHOMeAm OHOMeOMe

(c) Answer the following questions: It is possible for a compound to be chiral even though it lacks a carbon atom with four different groups. Using two nitro groups, one isopropyl group and one carboxy group as substituents, draw the structure of an optically active biphenyl that is void of a chiral carbon. i. ii. Deduce, giving reasons, whether or not the following molecules are optically active. H3C CH3 ČH(CH3)2 Quaternary ammonium salt NH2 Compound A НОСІНС OCH3 OCH3 Br Compound B
Ribose, a carbohydrate with the formula shown, forms a cyclic hemiacetal, which, in principle, could contain either a four-membered, five-membered, or six-membered ring. When D-ribose is treated with methanol in the presence of an acid catalyst, two cyclic acetals, A and B, are formed, both with molecular formula C,H,0, These are separated, and each is treated with sodium periodate (Section 10.8C) followed by dilute aqueous acid. Both A and B yield the same three products in the same ratios. он о CHO СНО H+ CH,OH A +B ÕH 1. NalO, 2.

Draw the structures of the following.
Start with the condensed structural formula CH3-CH=CH-CH2-CH3, and react it fırst with H20 in the presence of H2SO4 (as the catalyst), to produce TWO major substrate products. Then, take those two major substrate products, and use them as the substrates of the next reaction, by reacting each with K2Cr20, and H2SO4, to produce TWO FINAL MAJOR substrate products. [There are a total of two final major substrate products, not four.] The complete correct condensed structural formulas for the two major substrate products (after reaction step 1) are and The complete correct condensed structural formulas for the two final major substrate products (after reaction step 2) are and
