Ethynyl group
Introduction In organic chemistry, an '''ethynyl group''' is a functional group with the formula −C≡CH. It is the acetylene molecule with one fewer hydrogen atom. The name is also used for any compound containing that group, namely R−C≡CH where R is any other group of atoms. * '''Ethynyl group''' ('''HC≡C–'''), also designated as acetylenic group (from acetylene), and referred to in IUPAC chemical nomenclature as -yne suffix. Also sometimes designed as ''ethinyl'' in compounds (ethinylestradiol, ethisterone (ethinyltestosterone)). See main page alkynes. * '''Ethynyl radical''' ('''HC≡C·'''), the compound found in interstellar medium, and transiently on earth during chemical reactions. * '''Ethynyl carbanion''' acetylide ('''HC≡C−''')
