Methylidyne group
{{Short description|Chemical group (≡CH)}}
In organic chemistry, a methylidyne group or just methylidyne is a neutral part of a molecule (a substituent or functional group) with formula {{chem2|\tCH}}, consisting of a carbon atom bonded to a hydrogen atom by one single bond and to the rest of the molecule by one triple bond.

For example, a methylidyne group is present in n-methylidyne-1-hexanaminium, {{chem2|H3C\s(CH2)5\sN+\tCH}}.
The name "methylidyne" is also used for the methylidyne radical (carbyne) {{chem2|⫶CH}}, the same two atoms not bound to any other atom.
