WebAn alkyne is an electron-rich molecule with a high density of pi electrons; therefore, it is a good nucleophile that reacts readily with electrophiles. Thus, alkynes, like alkenes, also … WebAlkynes undergo addition reactions due to the presence of loosely held pi-electrons. Due to the presence of a triple bond in alkynes, halogens, water etc.can be added to them by the process of the addition reaction. …

In organic chemistry, alkynylation is an addition reaction in which a terminal alkyne ( −C≡CH) is added to a carbonyl group ( C=O) to form an α -alkynyl alcohol ( R2C (−OH)−C≡C−R ). [1] [2] When the acetylide is formed from acetylene ( HC≡CH ), the reaction gives an α- ethynyl alcohol. This process is often ... WebThus, by the proper choice of reagents, terminal alkynes may be converted either to methyl ketones (mercuric ion catalyzed hydration) or aldehydes (hydroboration followed by oxidation).
