Aniline (from Portuguese anil 'indigo shrub', and -ine indicating a derived substance) [6] is an organic compound with the formula C 6 H 5 NH 2. Consisting of a phenyl group ( −C 6 H 5 ) attached to an amino group ( −NH 2 ), aniline is the simplest aromatic amine .
Aniline is a benzenoid compound. The NH 2 group attached to the benzene ring means that there is a lone pair of electrons that can enter into conjugation with the benzene ring resulting in delocalization in the aniline. Aniline absorbs in the K (220 - 250 nm) and the B (250 - 290 nm) bands exhibited by benzenoid compounds.
Names Preferred IUPAC name. 3-Methoxyaniline [1] Other names meta-Anisidine; 3-Anisidine. ... It is one of three isomers of the methoxy-containing aniline derivative.
N-Methylaniline (NMA) is an aniline derivative. It is an organic compound with the chemical formula C 6 H 5 NH(CH 3). The substance is a colorless viscous liquid, Samples turn brown when exposed to air. The chemical is insoluble in water.
Below is a laboratory synthesis of 4-nitroaniline from aniline. The key step in this reaction sequence is an electrophilic aromatic substitution to install the nitro group para to the amino group. The amino group can be easily protonated and become a meta director. Therefore, a protection of the acetyl group is required.
N,N-Dimethylaniline (DMA) is an organic chemical compound, a substituted derivative of aniline. It is a tertiary amine, featuring a dimethylamino group attached to a phenyl group. This oily liquid is colourless when pure, but commercial samples are often yellow. It is an important precursor to dyes such as crystal violet.
Aniline Yellow Names Preferred IUPAC name. 4-(Phenyldiazenyl)aniline. Other names para-Aminoazobenzene ... Aniline Yellow is a yellow azo dye and an aromatic amine.
p-Anisidine condenses readily with aldehydes and ketones to form Schiff bases, which absorb at 350 nm.This colorimetric reaction is used to test for the presence of oxidation products in fats and oils, an official method for detecting them by the American Oil Chemists' Society. [9]
