🤓 Based on our data, we think this question is relevant for Professor Graham's class at SJU.

Solution: Deuterium (D) is an isotope of hydrogen, in which the nucleus has one proton and one neutron. This nucleus, called a deuteron, behaves very much like a proton, although there are observed differences in the rates of reactions involving either protons or deuterons (an effect called the kinetic isotope effect). Deuterium can be introduced into a compound via the process below:(a) The C—Mg bond in compound  3 can be drawn as ionic. Redraw 3 as an ionic species, with BrMg + as a counterion, and then draw the mechanism for the conversion of  3 to 4.
