Is bbr3 a lewis acid
Web1 mei 2024 · Lewis acids and bases can be classified by designating them as hard or soft. Acids and bases are not strictly hard or soft, since many ions and compounds are classified as intermediate. The categorizations are based on three factors: (1) charge density, or charge-to-size ratio (2) polarizability (3) covalent vs. ionic nature of interactions. WebBBr3 is a strong lewis acid as the bromine atom has much electron cloud to donate to other atoms, hence it is a strong lewis acid in nature. How BBr3 is acidic? In BBr3 lewis …
