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.
