==Methane substituents==
According to the above rules, a carbon atom in a molecule, considered as a substituent, has the following names depending on the number of hydrogens bound to it, and the type of bonds formed with the remainder of the molecule:
{| class="wikitable"
|-
| {{chem2|CH4}} ||  [[methane]] ||  no bonds
|-
| {{chem2|\sCH3}} ||  [[methyl group]] or methanyl ||  one single bond to a non-hydrogen atom
|-
| {{chem2|\dCH2}} ||  [[methylene group]] or methanylidene or methylidene ||  one double bond
|-
| {{chem2|\sCH2\s}} ||  [[methylene bridge]] or methanediyl or methdiyl ||  two single bonds
|-
| {{chem2|\tCH}} ||  [[methanylidyne group]] or methylidyne ||  one triple bond
|-
| {{chem2|\dCH\s}} ||  [[methine group]] or methanylylidene or methylylidene ||  one single bond and one double bond
|-
| {{chem2|>CH\s}} ||  [[methanetriyl group]] or methtriyl ||  three single bonds
|-
| {{chem2|\tC\s}} ||  [[methanylylidyne group]] or methylylidyne ||  one triple bond and one single bond
