Please help!!
7. (0) An unknown molecule Y has a molecular formula of CsH1002, a broad absorption in its IR spectrum from 3200 to 3550 cm region, and no absorption in the 1620 to 1780 cm region. No carbon atom in the structure Y has more than one oxygen atom bonded to it and Y can exist in two (and only two) stereoisomeric forms. What are the structures of these forms of Y?
