The percent of α- and β-D-mannopyranose isomer at equilibrium has to be calculated. Concept introduction: A mixture that has an equal amount of enantiomers is commonly known as a racemic mixture. Enantiomers have non-superimposable mirror images of one other and therefore; they rotate the plane of polarized light in the opposite but equal direction. The racemic mixture is optically inactive in nature. The property of a chiral compound in which the compound changes the orientation of the monochromatic light is known as specific rotation. This change in orientation takes place per unit distance-concentration of the product.

During the reaction, you observe the formation of three separate molecules instead of the single molecule obtained above. What is the likeliest other products that are formed? Draw them in the box provided.

3. For the reactions below, draw the arrows corresponding to the transformations and draw in the boxes the reactants or products as indicated. Note: Part A should have arrows drawn going from the reactants to the middle structure and the arrows on the middle structure that would yield the final structure. For part B, you will need to draw in the reactant before being able to draw the arrows corresponding to product formation. A. B. Rearrangement ΘΗ

2. Draw the arrows required to make the following reactions occur. Please ensure your arrows point from exactly where you want to exactly where you want. If it is unclear from where arrows start or where they end, only partial credit will be given. Note: You may need to draw in lone pairs before drawing the arrows. A. B. H-Br 人 C Θ CI H Cl Θ + Br O
