When D2 reacts with ethylene (C2H4) in the presence of a finely divided catalyst, ethane with two deuteriums, CH2D–CH2D, is formed. (Deuterium, D, is an isotope of hydrogen of mass 2). Very little ethane forms in which two deuteriums are bound to one carbon (for example, CH3–CHD2). Use the sequence of steps involved in the reaction (Figure 14.24) to explain why this is so.
