You are trying to determine the optical purity (% enantiomeric excess) of a compound tha you have just synthesized. You measure the rotation of plane-polarized light of a 0.5 g/ml solution and find the rotation to be +16.2 degrees (clockwise). Given the pure (-) isomer has a specific rotation of -45 degrees, what is the optical purity of the compound? Show you work.

The NMR spectrum of bromocyclohexane indicates a low field signal (1H) at δ 4.16. To room temperature, this signal is a singlet, but at -75 ° C it separates into two peaks of unequal area (but totaling one proton): δ 3.97 and δ 4.64, in ratio 4.6: 1.0. How do you explain the doubling in two peaks? According to the generalization of the previous problem, what conformation of the molecule predominates (at -75 ° C)? What percentage of the molecules does it correspond to? Solve all parts otherwise down vote and hand written solution
