The longest unbranched chain containing the functional group is the parent molecule, or simply the longest unbranched chain for alkanes. Remember that, the longest chain can go round a bend.

The rapid disappearance of the amber color of the bromine at room temperature is characteristic of reaction with alkenes. (colorless) (purple) (colorless ...

An unsolved challenge in catalysis is the efficient and selective functionalization of simple alkanes and plentiful hydrocarbon feedstocks. One promising approach since the late 1990’s is the use of ...

Alkanes, in contrast, do not have a functional group and are less reactive as a result. Complete combustion of alkenes produces carbon dioxide and water, provided there is a plentiful supply of ...
