List of Alkanes

Author: Hans Lohninger

Following is a list of alkanes showing their chemical formulas, their names, the number of isomers, and the melting and the boiling point. Please note that, except for the first four alkanes (n=1..4), their chemical names can be derived from the number of C atoms by using Greek numerical prefixes denoting the number of carbons and the suffix "-ane".
