2-Bromopentane is a bromoalkane and isomer of bromopentane. It is a colorless liquid. 2-Bromopentane is chiral and thus can be obtained as either of two stereoisomers designated as ( R )-2-bromopentane and ( S )-2-bromopentane, or as a racemic 1:1 mixture of the two enantiomers .
Bromopentanes are a group of bromoalkanes consisting of pentane isomers with one or more hydrogen atoms replaced by bromine atoms. They have the formula C 5 H 12–n Br n, where n = 1–12 is the number of bromine atoms. They are colorless liquids.
In this approach: identify the chiral center, label the four atoms directly attached to the stereogenic center in question, assign priorities according to the sequence rule ( from 1 to 4), rotate the molecule until the lowest priority (number 4) substituent is away from the observer/viewer, draw a curve from number 1 to number 2 to number 3 ...

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. It is a colorless liquid with a pleasant odor.
A chiral molecule is a type of molecule that has a non-superposable mirror image. The feature that is most often the cause of chirality in molecules is the presence of an asymmetric carbon atom. [16] [17] The term "chiral" in general is used to describe the object that is non-superposable on its mirror image. [18]
2-Bromohexane is the organobromine compound with the formula CH 3 CH(Br)(CH 2) 3 CH 3. It is a colorless liquid. The compound is chiral. Most 2-bromoalkanes are prepared by addition of hydrogen bromide to the 1-alkene. Markovnikov addition proceeds in the absence of free-radicals, i.e. give the 2-bromo derivatives. [2]
R-S isomerism of thalidomide. Chiral center marked with a star(*). Hydrogen (not drawn) is projecting behind the chiral centre. Enantiomers are molecules having one or more chiral centres that are mirror images of each other. [2] Chiral centres are designated R or S. If the 3 groups projecting towards you are arranged clockwise from highest ...
