The meaning of the designations D and L as used to specify the configuration of a monosaccharide should be explained. Concept Introduction: In a monosaccharide, if at the last stereocenter the hydroxyl group is at right in the Fischer projection, the monosaccharide is known to have D configuration. Opposite to it if the hydroxyl group is at left, the monosaccharide will have L configuration.

Draw the major substitution products you would expect for the reaction shown below. If substitution would not occur at a significant rate under these conditions, check the box underneath the drawing area instead. Be sure you use wedge and dash bonds where necessary, for example to distinguish between major products. Note for advanced students: you can assume that the reaction mixture is heated mildly, somewhat above room temperature, but strong heat or reflux is not used. Cl Substitution will not occur at a significant rate. Explanation Check :☐ O-CH + Х Click and drag to start drawing a structure.
