Yes, but that name is derived from calling the whole class of compounds “paraffins”. They are more properly called alkanes but the term “paraffin” is used interchangeably. Chemistry has a nomenclature system but the old names stick, especially with the general public and when the material being talked about is a mixture. Kerosene, for example, is a mixture of alkanes with chain lengths of 6 to 20 carbons. Six carbons chains can contain a straight chain hydrocarbon called hexane but a chain of 6 carbons doesn’t have to be straight in order to fall into the alkanes. It can be in a branched configuration and still fit into the formula CnH2n+2 resulting in 5 different compounds…n-hexane, 2-methylpentane, 3-methylpentane, 2,2-dimethylbutane, and 2,3-dimethylbutane. With a C20 molecule, there is the possibility of 366319 different unique isomers. Wax with a up to a C40 chain has 62,481,801,147,341. They can’t all be listed so we just give the whole bunch of material the name “alkanes” and “paraffins” before that.
