I'm trying to understand this mechanism and the R/S configurations for my lab.... not trying to just write down the answer given to us.
Here is what I have:
I chose that the bromine attacks from the top, creating a Bromonium ion. The next Br- comes in from the BOTTOM, because the first bromine takes up too much room. The top bromine would be pointing up, and then bottom one point down....
Is that correct?
I understand how to write R/S configurations, but I don't think that the mechanism is correct, due to the fact that I'm getting two S configurations....
I'm a little confused as to the right hand carbon.... what did I do wrong to get 2 R's??
