WebApr 6, 2024 · The hydrogen atoms attached to the the triple bond of alkynes are acidic in nature. (1) Formation of alkali metal acetylides : Ethyne and other terminal alkynes or 1-alkynes react with strong bases such as sodium metal at 475 K or sodamide in liquid ammonia at 196 K to form sodium acetylides with evolution of H 2 gas. WebCarbon atoms may thus form bonds to as many as four other atoms. For example, in methane (CH _4 4 ), carbon forms covalent bonds with four hydrogen atoms. Each bond corresponds to a pair of shared electrons (one from carbon and one from hydrogen), giving carbon the eight electrons it needs for a full outer shell. Hydrocarbons
