Which of the following five substrates is the most likely to be the substrate in an S_N1 reaction? B)(I C)(II D)(I

Question

Quizplus · Accepted Answer

Based on the naming convention of the reaction, S_N1, it is likely a substitution reaction (S) with a single substitution (SS1), involving an unsaturated substrate (U1) with a nucleophile (NS1), and a single bond is broken (B1) in the substrate. Looking at the options, only (I) fits this description as it is unsaturated and has a single bond that can be broken. The other options (II), (III), (IV), and (V) either do not have unsaturation, have multiple bonds that can be broken, or are not suitable as a nucleophile.
