Ethynylbenzene

Ethynylbenzene, also known as phenylacetylene, has the chemical formula C₆H₅C≡CH. It consists of a benzene ring attached to an ethynyl group. This compound is a colorless, viscous liquid. As a terminal alkyne, it exhibits reactions typical of this functional group, such as undergoing coupling reactions like the Sonogashira coupling, which is a powerful tool for forming carbon-carbon bonds in organic synthesis. It is also used in the production of polymers and as a precursor to other organic compounds. For example, it can be polymerized to form polyphenylacetylene, a conductive polymer. Its pleasant odor has also led to its use in perfumery. Explore searchable catalogue of hundreds of molecules, including details on how models were generated. NotesIf you happen to break something, use superglue to fix it. It will make the broken part even stronger.I decided to go with the ball-and-stick type, as it is easiest to color, is rigid, and looks awesome.The model represents the major resonance
