Methylidyne group
In chemistry, a methylidyne group or just methylidyne is a neutral part of a molecule with formula ≡CH, 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, −5−≡CH
The name "methylidyne" is also used for the methylidyne radical ⫶CH, the same two atoms not bound to any other atom.
