Assume that you have carried out a radical chlorination reaction on (R)-2- chloropentane and have isolated (in low yield) 2,4-dichloropentane. (a) Show the starting material and product. (b) How many stereoisomers of the product are formed and in what ratio? (c) Are any of these stereoisomers optically active? (d) Propose a mechanism for this reaction. Use arrows to show the flow of electrons
