2-Bromobutane is an isomer of 1-bromobutane. Both compounds share the molecular formula C 4 H 9 Br. 2-Bromobutane is also known as sec -butyl bromide or methylethylbromomethane. Because it contains bromine , a halogen, it is part of a larger class of compounds known as alkyl halides .

This results in S N 1 reactions usually occurring on atoms with at least two carbons bonded to them. [2] A more detailed explanation of this can be found in the main SN1 reaction page. S N 2 reaction mechanism. The S N 2 mechanism has just one step. The attack of the reagent and the expulsion of the leaving group happen simultaneously.
In chemistry, solvolysis is a type of nucleophilic substitution (S N 1/S N 2) or elimination where the nucleophile is a solvent molecule. [1] Characteristic of S N 1 reactions, solvolysis of a chiral reactant affords the racemate.
An example of a reaction proceeding in a S N 1 fashion is the synthesis of 2,5-dichloro-2,5-dimethylhexane from the corresponding diol with concentrated hydrochloric acid: [8] As the alpha and beta substitutions increase with respect to leaving groups, the reaction is diverted from S N 2 to S N 1.
In S N 2 reactions, there are a few conditions that affect the rate of the reaction. First of all, the 2 in S N 2 implies that there are two concentrations of substances that affect the rate of reaction: substrate (Sub) and nucleophile. The rate equation for this reaction would be Rate=k[Sub][Nuc].
The molecular formula C 4 H 9 Br, (molar mass: 137.02 g/mol, exact mass: 135.9888 u) may refer to: 1-Bromobutane; 2-Bromobutane; tert-Butyl bromide;
[6] [7] The key feature of the mechanism is an initial rate-determining pre-equilibrium to form an encounter complex ML 6-Y from reactant ML 6 and incoming ligand Y. This equilibrium is represented by the constant K E: ML 6 + Y ⇌ ML 6-Y. The subsequent dissociation to form product is governed by a rate constant k: ML 6-Y → ML 5 Y + L
