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.
