Alkoxide ions are negatively charged species formed when an alcohol loses a hydrogen ion (H⁺). They have the general formula R-O⁻, where R represents an alkyl group. Alkoxide ions are important in organic chemistry, particularly in reactions involving nucleophiles, as they can readily react with electrophiles. These ions are commonly generated by reacting alcohols with strong bases, such as sodium hydride or sodium metal. Alkoxides can also serve as intermediates in various chemical processes, including the synthesis of ethers and the preparation of organometallic compounds. Their reactivity makes them valuable in both laboratory and industrial applications.
