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
