The FALSE statement is " in general, the R enantiomer will rotate plane polarized light to the right and the S enantiomer will rotate light to the left"
Reason: optical rotation is the property of a molecule and it has no relationship with the configuration of the molecule. R enantiomer can rotate light in either direction and this holds true for S enantiomer as well.
Which of the following is FALSE regarding the optical activity? Enantiomers rotate plane polarize light to...
optical activity problems.. please show all steps i dont understand You have a sample (Sample X) which is a mixture of +/- Carvone. The solution was made by dissolving 4.50 g of the sample in enough methanol to bring the volume of solution to 10,0 ml. Some of the solution is placed in a 100 cm polarimeter cell and its optical rotation is measured at 25°C using light of the sodium D line wavelength (589.6 nm). The observed rotation is...
A. Enantiomers: Certain substances have the unique property of rotating the plane of plane-polarized light. Such light rotation is detectable with the aid of a polarimeter. In order for a molecule to be optically active it must be chiral. Chiral objects lack a plane of symmetry and are non-superimposable on their mirror images. A sp?- hybridized carbon atom can fulfill these requirements if all four of its substituents are different. 1. Methane a) Prepare a methane molecule and then substitute...
Please help with pre-lab questions. Pre-Lab Questions: 1. A sample of 2-butanol has a specific rotation of +3.25. Determine the optical purity (%ee) and percent composition of this sample (see Mohrig section 17.4). The specific rotation of pure (+)-2-butanol is +13.0°. 2. The equation for the formation of the diastereomeric salts is shown in the background information (performed in Part A of the procedure). Write this chemical equation in your notebook, then ALSO write a balanced equation for the formation...
Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
