Show all possible products of the syn dihydroxylation of the alkene below. What is the relationship between the two products? Is this an example of a stereoselective or stereospecific reaction, or neither? Explain briefly.
Homework Answers
vinyl benzene reacts with osmium oxide and water to form dihydroxide. The dihydroxide added in syn fashion therefore only cis product is formed. since trans isomer is not formed, only cis isomer is formed reaction is the stereospecific reaction
product A and B pair of enantiomers
Enantiomers are pair of compound have mirror-image relationship and not superimposable to each other.

1. Bromination of an alkene is restricted to a syn addition. In this problem you will design an experiment to validate or provide evidence that alkene bromination undergoes syn addition You will use the following starting alkene a) trans-stilbene b) cis-stilbene A. Draw the mechanisms showing all electron flows (curved arrows) and the cyclic halonium intermediate to predict the stereochemical products of the bromination reaction for (a) trans-stilbene and (b) cis-stilbene formed from syn addition.

What is a stereoselective reaction? What is a chiral center? What are R and S? What physical property allows us to distinguish between diastereomers but not enantiomers? What are syn and anti addition? How do they add? What product results from each? Provide the R and S configurations for both possible products. What is the addition that is most likely to occur? Why?

1. Synthetic organic chemists have established clever ways for probing the mechanisms of chemical reactions. In general, a preference for anti- periplanar elimination is observed; however, under some conditions the syn-periplanar elimination product can be observed. How do chemists tell the difference between anti-and syn-periplanar eliminations? Let's find out! The reaction of the substrate below under E2 conditions (NaOEt in ethanol) will give different products by syn- and anti- elimination mechanisms. By analyzing the distribution of the products, organic chemists...
