The reaction of 1,3-pentadiene with hydrogen chloride (HCI) gives the product shown below (as a racemate). However, the reaction with deuterium chloride (DCI) produces two products, A and B (also as racemates), and the ratio of these is temperature dependent. Which product, A or B is favored at low temperatures (0°C) and What happens to the ratio at higher temperatures (40°C)? Explain these in terms of kinetic vs thermodynamic control. (20 points d.
