question 84

Essay

An optically active hexose (A),C₆H₁₂O₆,was degraded to an optically active pentose (B),C₅H₁₀O₅,by the following series of reactions: Compound (B)was degraded to an optically active tetrose (C),C₄H₈O₄,through the same series of reactions as shown above; then (C)was oxidized with HNO₃ to yield meso tartaric acid.
Give possible structure for (A)and (B).
