When (R)-6-bromo-2,6-dimethylnonane is dissolved in CH3OH,nucleophilic substitution yields an optically inactive solution. When theisomeric halide (R)-2-bromo-2,5-dimethylnonane is dissolved in CH3OHunder the same conditions, nucleophilic substitution forms an opticallyactive solution. Draw the products formed in each reaction, and explainwhy the difference in optical activity is observed.
Classify the following sigmatropic rearrangement and determine whether it takes place readily under thermal or photochemical reaction conditions.
Draw a detailed mechanism for the FeBr3@catalyzed reaction of ethylbenzene with bromine, and show why the sigma complex (and the transition state leading to it) is lower in energy for substitution at the ortho and para positions than it is for substitution at the meta position.
