From the given specific rotation of α-D-glucose , the specific rotation of α-L-glucose has to be found. Concept Introduction: Specific rotation is the property of chiral compound that can be defined as the change in arrangement of monochromatic plane-polarized light per unit distance-concentration product, as the light passes through the sample of compound in a solution. Specific rotation of compound is calculated by, [α] λ T = α l ( dm)×c (g/100mL) where, [α] λ T -specific rotation (at T and λ) α-observed rotation c-concentration of the sample l-length of the sample tube

For each reaction below, decide if the first stable organic product that forms in solution will create a new CC bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. ?

Predicting As the lead product manager at OrganometALEKS Industries, you are trying to decide if the following reaction will make a molecule with a new C - C bond as its major product: H₂N O H 1. ? 2. H3O+ If this reaction will work, draw the major organic product or products you would expect in the drawing area below. If there's more than one major product, you can draw them in any arrangement you like. Be sure you use wedge and dash bonds if necessary, for example to distinguish between major products with different stereochemistry. 0 If the major products of this reaction won't have a new CC bond, just check the box under the drawing area and leave it blank. فا Explanation Check Click and drag to start drawing a structure.
