Chemistry - 20.1 & 20.2 Vocab NP - Hydrocarbons & Unsaturated Hydrocarbons

homologous series

a group of compounds in which there is a constant increment of change in molecular structure from one compound in the series to the next

alkyne

a hydrocarbon containing a carbon-carbon triple bond; alkynes are unsaturated hydrocarbons

alkene

a hydrocarbon containing one or more carbon-carbon double bonds; alkenes are unsaturated hydrocarbons

alkane

a hydrocarbon containing only single covalent bonds; alkanes are saturated hydrocarbons

alkyl group

a hydrocarbon substituent; the methyl group (—CH3) is an alkyl group

straight chain alkane

a saturated hydrocarbon that contains any number of carbon atoms arranged one after the other in a chain

condensed structural formula

a structural formula that leaves out some bonds and/or atoms; the presence of these atoms or bonds is understood

branched-chain alkane

an alkane with one or more alkyl groups attached to the parent structure

substituent

an atom or group of atoms that can take the place of a hydrogen atom on a parent hydrocarbon molecule

saturated compound

an organic compound in which all carbon atoms are joined by single covalent bonds; it contains the maximum number of hydrogen atoms per carbon atom

hydrocarbon

an organic compound that contains only carbon and hydrogen

unsaturated compound

an organic compound with one or more double or triple carbon-carbon bonds
