Products of radical bromination and mechanism
My prof says that I am missing my R/S. I can clearly see my chiral centres, but how do I determine the orientation of the H? Red is the major product, blue is the minor product, and magenta is the very minor product.


You don't determine the orientation of the H you just acknowledge the formation of both the R and S stereo isomers in your products in 50/50 proportions.


  My prof says that I am missing a propagation step with another bromine-bromine molecule. I would greatly appreciate your input!


All you need to show is the organic radical reacting with diatomic bromine to form you brominated molecule and another bromine radical.
