Hiiliketjussa is a Finnish term used in chemistry to describe the carbon chain backbone of organic molecules. The word combines hiili (carbon) and ketju (chain), with the locative suffix -ssa indicating “in” or “within.” In practice, hiiliketjussa refers to the sequence of carbon atoms that forms the main skeleton of a molecule, distinct from functional groups or substituents attached to it.
Etymology and meaning: The root hiili means carbon (and by extension coal), while ketju means chain. The
Usage in chemistry: The carbon chain can be straight (linear) or branched. In IUPAC nomenclature, the length
