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.

How do you name alkanes with functional groups?

Three Rules for Naming Alkanes. Choose the longest, most substituted carbon chain containing a functional group. A carbon bonded to a functional group must have the lowest possible carbon number. If there are no functional groups, then any substituent present must have the lowest possible number.

Are alkynes functional groups?

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.
