alswering these questions. 1. If the bromination of trans-stilbene proceeded by syn addition what isomer(s) of stilbene dibromide would be formed? 2. If the bromination of trans-stilbene proceeded by anti addition what isomer(s) of stilbene dibromide would be formed? 3. Which isomer(s) of stilbene dibromide would be formed if the reaction followed Mechanism 4? Mechanism 4: Bromination is a multi-step process. In this mechanism, the pi bond attacks the bromine molecule as in Mechanism 1. Some time after the carbocation...

What is the theoretical yield for the bromination of trans-Stilbene reaction? Setting up the experiment: 18mg of trans-Stilbene and 103mg of polymer supported brominating agent & 2mL chloroform Monitoring the experiment: 5mg of trans-Stilbene in 1ml of Chloroform
what are some possible errors that can affect percent yield in the bromination of trans-stilbene?

Draw the reaction and reaction mechanism for the reaction of
both
cis
and
trans
stilbene with Br2
as part of your prelab procedure.
Note: I'm not sure what the
mechanisms look like so that's why I'm having trouble with the
products. Please, if you can, draw out the mechanisms for both of
these!! Thanks.

Below are three possible mechanisms for the bromination of
trans-stilbene. All mechanisms are possible on paper. Study each
mechanism and decide what the stereochemical outcome of each would
be and draw the appropriate product (syn, anti, or a mix of both).
Decide which mechanism is most consistent with your data from the
experiment. This work should all be recorded in your lab
notebook.
