We’ve already learned a bit about substitution reactions in organic chemistry and the two different paths they can follow: SN1 and SN2. In order to better predict the products of a substitution reaction and understand how they work, we need to be able to figure out which mechanism a reaction is likely to follow. In this episode of Crash Course Organic Chemistry, we’ll deepen our knowledge of substitution reactions by looking at factors like substrate structure and reaction conditions to determine whether SN1 or SN2 is the more likely mechanism.
