For the reaction shown, which one of the following statements is correct.

Question

Quizplus · Accepted Answer

The reaction shown is a substitution (S) reaction, with one substrate (S1) and one nucleophile (N). It is also a unimolecular (U1) reaction, which means the rate-determining step involves only one molecule. The leaving group (L) is indicated by a superscript on the substrate. In this case, L is Br. The reaction has a second order kinetics (B02), meaning it involves two molecules in the rate-determining step. The reaction is accelerated in polar solvent because the substrate and nucleophile are both charged or polar molecules, and polar solvents stabilize the transition state and help the reaction go faster.
