Benzenediazonium cation Key Reactions: Synthetic Uses of Aryl Diazonium Salts: Sandmeyer Reaction: It can be converted to aryl halides (Ar-Cl, Ar-Br, Ar-CN) by treating them with corresponding copper(I) salts like CuCl, CuBr, or … Read more
Basicity of Amines: Amines are organic compounds derived from ammonia (NH₃) by replacing one or more hydrogen atoms with alkyl or aryl groups. The basicity of amines arises from the lone pair of electrons on the nitrogen atom, which can accept a proton (H⁺). The basicity of an amine is typically expressed as the pKa … Read more
Aromatic amines are organic compounds derived from ammonia (NH₃) where one or more hydrogen atoms are replaced by an aromatic ring, such as benzene or naphthalene. The general formula is Ar-NH₂, where Ar represents an aromatic group. Types and Classification Based on the Number of Aromatic Groups: Primary Aromatic Amine: One aromatic group attached to … Read more
The acidity of aromatic acids is determined by the ability of the molecule to donate a proton (H⁺) from the carboxyl group. After losing a proton, the molecule forms a carboxylate anion (Ar-COO⁻). The stability of this anion is a key factor in determining the acid strength. Key Factors Influencing Acidity of Aromatic Acids: Resonance … Read more
Benzoic acid, like other carboxylic acids, undergoes several important reactions of benzoic acid/ aromatic acids. These reactions are primarily due to the reactivity of the carboxyl group (-COOH). Formation of Benzoate Salts – Important Reactions of Benzoic Acid/ Aromatic Acids: Reaction: Benzoic acid reacts with bases (e.g., NaOH) to form benzoate salts. Example: C6H5COOH+NaOH→C6H5COONa+H2O Esterification: … Read more
Definition of Aromatic Acids: Aromatic acids are organic compounds containing a carboxylic acid group (-COOH) attached to an aromatic ring, such as benzene or naphthalene. They exhibit properties characteristic of both carboxylic acids and aromatic compounds. Types and Classification of Aromatic Acids: Benzoic Acid Derivatives: Contain a carboxylic acid group directly attached to a benzene … Read more
