In the S N 1 reaction the nucleophile attacks after the rate-limiting step is over, whereas in S N 2 the nucleophile forces off the leaving group in the limiting step. In other words, the rate of S N 1 reactions depend only on the concentration of the substrate while the S N 2 reaction rate depends on the concentration of both the substrate and ...

The rate equation for this reaction would be Rate=k[Sub][Nuc]. For a S N 2 reaction, an aprotic solvent is best, such as acetone, DMF, or DMSO. Aprotic solvents do not add protons (H + ions) into solution; if protons were present in S N 2 reactions, they would react with the nucleophile and severely limit the reaction rate.
This difference arises from acid/base reactions between protic solvents (not aprotic solvents) and strong nucleophiles. While it is true that steric effects also affect the relative reaction rates, [12] however, for demonstration of principle for solvent polarity on S N 2 reaction rates, steric effects may be neglected.
In chemistry, a concerted reaction is a chemical reaction in which all bond breaking and bond making occurs in a single step. Reactive intermediates or other unstable high energy intermediates are not involved. [1] [2] Concerted reaction rates tend not to depend on solvent polarity ruling out large buildup of charge in the transition state.
The tentative rate equation determined by the method of initial rates is therefore normally verified by comparing the concentrations measured over a longer time (several half-lives) with the integrated form of the rate equation; this assumes that the reaction goes to completion. For example, the integrated rate law for a first-order reaction is
The two reactions are named according tho their rate law, with S N 1 having a first-order rate law, and S N 2 having a second-order. [2] S N 1 reaction mechanism occurring through two steps. The S N 1 mechanism has two steps. In the first step, the leaving group departs, forming a carbocation (C +). In the second step, the nucleophilic reagent ...
Ammonolysis refers to solvolysis by ammonia, but can also describe nucleophilic attack by ammonia more generally. Ammonia boils at −33 °C, and, as such, is rarely used as a solvent in its pure form. It is, however, readily miscible with water, and is commonly used in the form of a saturated aqueous solution. For this reason, ammonolysis may ...
