10.50 Consider the following radical process, called athiol-ene coupling reaction, in which an alkene is treatedwith a thiol (RSH) in the presence of a radical initiator: (a) Draw a plausible

mechanism for this process, showing the initiation and propagation steps. The radical polymerization of styrene (to make polystyrene) generates new chirality centers. Draw a mechanism forthe polymerization, indicate initiation, propogation and termination steps. How many stereoisomersare there of a polystyrenemolecule made up of 100styrene units?
