CH 110K Lecture Notes - Lecture 3: Polarimetry, Enantiomer, Bromine
Document Summary
10/4/16 12:47 pm: enantiomers non super imposable mirror images, only differ in: odor and polarimetry, diastereomers very different chemical properities. : tests by seeing if they smell different: but we have to have proper sniffing technique (wafting) Small percent of the population that can"t distinguish between the two enantiomers. (it"s a genetic issue): polarimetry, polarized light will rotate a certain number of degrees. Either to the right or to the left: they are visual and very sensitive. The enantomiers should be equal and opposite, however they are very sensitive and can detect very slight differences such as a scratch or impurity on the test tube. It"s okay if the numbers aren"t exactly the same. No because of the double bond: energy comes form light, e=plancks constant * frequency of the light, ultraviolet. But there"s not enough ultraviolet radiation from a lab light bulb for the reaction to work by itself.
