Please answer in full
An unknown pentose (C_5H_10O_5) A is treated with conc. HNO_3 giving optically inactive diacid B. Kiliani-Fischer chain elongation of A results in the formation of two epimeric hexose sugars, C and D, whose diacids (from HNO_3 oxidation) are both optically active (E and F, respectively). When subjected to the Fisher sequence (C1 - C6 interchange), hexose D affords L-glucose. Treatment of pentose A with aqueous bromine gives G, which undergoes decarboxylation in the presence of iron...
