Nabh4 reduces double bond
WitrynaAnswer: LiAlH4, NaBH4 and DiBAL-H all act as reducing agents and all of them reduce by providing hydride ion(not exactly if we think in context of molecular orbitals but can … WitrynaThe carbon-oxygen double bond is highly polar, and the slightly positive carbon atom is attacked by the hydride ion acting as a nucleophile. A hydride ion is a hydrogen atom with an extra electron - hence the lone pair. Nucleophile: A species (molecule or ion) which attacks a positive site in something else. Nucleophiles are either fully ...
