The number of alkanes (CXnHX2n+2 C X n H X 2 n + 2) as constitutional isomers (structural isomers) and as steric isomers is calculated by Polya's theorem (G. Polya and R. C. Read, Combinatorial Enumeration of Groups, Graphs, and Chemical Compounds, Springer (1987)).
For example, there are two structural isomers with the molecular formula C3H7Br. In one of them the bromine atom is on the end of the chain, whereas in the other it’s attached in the middle. If you made a model, there is no way that you could twist one molecule to turn it into the other one.
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.
The eighth possible structural isomer for the bromopentane is 1 - 1 - bromo - 2,2 - - 2,2 - dimethylpentane which has the bromine atom attached to the first carbon atom and two methyl groups to the second carbon atom. The structure is as follows, (CH3)3C − CH2 − Br (C H 3) 3 C − C H 2 − B r.
Solution. Bromo pentane: It contains 5 carbon atoms with -Br functional group. The structure is given below: CH3CH2CH2CH2CH2Br. Isomers of Bromopentane are:
One in a series of videos on haloalkanes (alkyl halides), it looks at the structures and names of the 11 isomers of bromopentane (C5H11Br).
Pentane, 1-bromo- Formula: C 5 H 11 Br. Molecular weight: 151.045. IUPAC Standard InChI: InChI=1S/C5H11Br/c1-2-3-4-5-6/h2-5H2,1H3. IUPAC Standard InChIKey: YZWKKMVJZFACSU-UHFFFAOYSA-N.
