Concept explainers

Alkanes and Cycloalkanes

Alkanes are saturated organic compounds which are made up of C and H atoms. Alkanes have the general formula of CnH2n+2. Alkane contains sp3 hybridized carbon atoms with four sigmas (σ) bonds & every hydrogen atom is connected with one of the carbon atoms. The size of the alkane could be determined by the number of carbon atoms located in it.

We have learned that isomers (molecules with the same molecular formula) can have different relationships, and these relationships can be made more clear by comparing IUPAC names. Constitutional isomers will differ in the main part of the name. Stereoisomers will differ only in the stereochemical prefix part of the name (cis/trans). Conformational isomers will actually have the same name, but different energies. Two structures that have the same names and the same energies are identical.
