A compound or ionic species which can accept an electron pair from a donor compound.
〔化〕路易斯酸
Example sentencesExamples
- In simple additions, the carbonyl compounds can behave as both Lewis acids and Lewis bases depending on what reagents are present.
- Like the Brönsted superacids, Lewis superacids are simply very strong Lewis acids.
- In this electrophilic aromatic substitution, the first electrophile is the Lewis acid that accepts the halogen from an alkyl halide (the nucleophile).
- In a coordinate covalent bond, both electrons are donated by the Logan, a Lewis base, to the metal atom, a Lewis acid.
- A Lewis acid, such as aluminum chloride, is often the catalyst used for this reaction.

Origin

1940s: named after Gilbert N. Lewis (1875–1946), American chemist.
