Bromocyclopentane is a derivative of cyclopentane, an alkyl halide with the chemical formula C 5 H 9 Br. It is a colorless to light yellow liquid at standard temperature and pressure . Uses
A reaction mechanism was first introduced by Christopher Ingold et al. in 1940. [3] This reaction does not depend much on the strength of the nucleophile, unlike the S N 2 mechanism. This type of mechanism involves two steps. The first step is the ionization of alkyl halide in the presence of aqueous acetone or ethyl alcohol.
With standard S N 1 reaction conditions the reaction outcome is retention via a competing S N i mechanism and not racemization and with pyridine added the result is again inversion. [5] [3] S N i reaction mechanism Sn1 occurs in tertiary carbon while Sn2 occurs in primary carbon
An example of a substitution reaction taking place by a so-called borderline mechanism as originally studied by Hughes and Ingold [6] is the reaction of 1-phenylethyl chloride with sodium methoxide in methanol. The reaction rate is found to the sum of S N 1 and S N 2 components with 61% (3,5 M, 70 °C) taking place by the latter.
Both associative and dissociative mechanisms have been observed. [4] [5] Associative substitution, for example, is typically applied to organometallic and coordination complexes, but resembles the Sn2 mechanism in organic chemistry. The opposite pathway is dissociative substitution, being analogous to the Sn1 pathway.

The bimolecular nucleophilic substitution (S N 2) is a type of reaction mechanism that is common in organic chemistry. In the S N 2 reaction, a strong nucleophile forms a new bond to an sp 3-hybridised carbon atom via a backside attack, all while the leaving group detaches from the reaction center in a concerted (i.e. simultaneous) fashion.
