Frequently Asked Questions
No, it is an extremely rare and highly specialized term used only in advanced organic chemistry.
Ethynylation specifically adds an —C≡CH group. Alkynylation is a broader term for adding any alkyne group (—C≡C—R).
Absolutely not. It is only relevant for chemists and students in very advanced synthetic chemistry courses.
Yes, in technical contexts. The verb form 'to ethynylate' is used, meaning to subject a compound to an ethynylation reaction.
A chemical reaction that introduces an ethynyl group (—C≡CH) into a molecule.
