Alkanes are compounds that consist entirely of atoms of carbon and hydrogen (a class of substances known as hydrocarbons) joined to one another by single bonds. ... Alkane sequences form the inert framework of most organic compounds. For this reason, alkanes are not formally considered a functional group.

Does alkenes contain functional group?

Alkanes are not usually considered as functional groups; instead, an alkane is a compound that lacks functional groups. The functional group in an alkene is a carbon-carbon double bond. ... The names of these compounds form the root names of other compounds having the same number of carbon atoms in a continuous chain.

Are alkynes a functional group?

Alkynes are organic molecules made of the functional group carbon-carbon triple bonds and are written in the empirical formula of CnH2n−2. They are unsaturated hydrocarbons.
