For the hydrocarbons, they're compounds in which each homolog differs incrementally in their C and H-atoms and can be represented by generalized formulas, for example:(where "n" is a counting number).
The formula for linear alkane hydrocarbons is CnH2n+2
The formula for linear mono alkene hydrocarbons is CnH2n
The formula for linear mono alkyne hydrocarbons is CnH2n-2
They are other homologous series as well
In order to determine which homologous series a molecule is from, we must take notice of the name ending. For e.g. 'ethene' if from the homologous series called the 'Alkenes' because it has the same name ending i.e. 'ene.' Therefore 'propane' is an Alkane because it carries the same name ending i.e. 'ane.'
propene or cyclopropene dependant on bonding
Propane is the common name---I have never heard of it called anything else. Natural gas contains propane, but there is typically more methane and ethane in natural gas than there is propane.
Cerium belongs to the lanthanide series of chemical elements, which are part of the f-block in the periodic table.
The "ene" suffix in ethene and propene indicates that these are hydrocarbons with a double bond between carbon atoms. The positioning of the double bond is implied in the name by the number of carbon atoms in the molecule (ethyl for ethene and propyl for propene). This naming system follows the rules of IUPAC nomenclature for organic compounds.
Chlorine belongs to the halogen family.
propene or cyclopropene dependant on bonding
The chemical name for Polypropylene is poly(propene).
Propane is the common name---I have never heard of it called anything else. Natural gas contains propane, but there is typically more methane and ethane in natural gas than there is propane.
The IUPAC name for pentane is pentane. Pentane is a saturated chain of five carbon (C) atoms with the formula C5H12. Specifically, using the IUPAC name, pentane refers to the n-pentane isomer.
