For medicinal substances: sodium chloride, formaldehyde solution, ascorbic acid - the general reaction of authenticity is the reaction with?A) Iron (III) chlorideB) Silver nitrateC) ChloramineD) Sodium nitriteE) Potassium permanganateFor 20.7 the solutions for part c and d dont seem right. Shouldn't reacting with 1 eq of H2 just take away the C=C bond and not the C=O bond. (H2 reduces C=C selectively to form a ketone according to page 738. Also the both the C=C and C=O bond should be reduced if excess H2 is used

It is thought to block the release of histamine, which prevents the sequence of events leading to swelling, itching, and constriction of bronchial tubes. Cromolyn sodium is synthesized in the following series of steps. Treatment of one mole of epichlorohydrin with two moles of 2,6-dihydroxyacetophenone in the presence of base gives I. Treatment of I with two moles of diethyl oxalate in the presence of sodium ethoxide gives a diester II. Saponification of the diester with aqueous NaOH gives cromolyn sodium. Q. Is cromolyn sodium chiral? If so, which of the possible stereoisomers are formed in this synthesis?
