If (Z)-3,4-dimethyl-3-hexene reacts with a peroxyacid. What is the stereochemical outcome of the major product(s)? achiral product enantiomers, racemic meso compound diastereomeric mixture single enantiomer

Which stereoisomer of 3-hexene forms a meso compound when it reacts with Br2?

Stereochemistry of hydroboration. There are two products that result from this reaction. Products 1 and 2 are stereoisomers of each other. The first product is thermodynamically more stable than the second product. Draw how the two products will look like. Also draw the most stable conformation of the first product. OH J 1. 9-BBN, THF 2. H₂0₂, H₂O, NaOH

see these instructions. Consider stereochemistry and enter either enantiomer (but not both) if a racemic mixture of products forms. If a mixture of two diastereomers is expected, enter either (but not both). 1. MgCl 2. H₂O

Predict the neutral product of treating the given alkene with the reagents shown. Only draw one enantiomer if more than one is possible. Clearly indicate stereochemistry by drawing wedge‑and‑dash bonds. Include hydrogens on chirality centers.

Identify the reactants and products for the following reaction. Include predicted stereochemistry. (R)-2-butylchloride + CH3S¯→

Starting from the structure below (sighting down the indicated bond), rotate the back carbon to provide the structure in the conformation that will be capable of an E2 elimination. R/S stereochemistry is graded. I H. H I I I I I I Ph Br Ph I I CH3 Drawing I I Ø
