CH2OH он он In the box below, draw the open-chain structure (as a Fischer projection corresponding to this Haworth projection of the cyclic hemiacetal. You may draw your Fischer projection without using wedged or hashed bonds. Align the Fischer projection vertically, e.g. . Show explicitly the bonds to any hydrogens attached to chiral carbons. Do not show bonds to other hydrogens. .A start structure for you modify is provided in the sketcher.
