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.
Carbonic acid equilibria are important for acid–base homeostasis in the human body. An amino acid is also amphoteric with the added complication that the neutral molecule is subject to an internal acid–base equilibrium in which the basic amino group attracts and binds the proton from the acidic carboxyl group, forming a zwitterion .
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.
Acetanilide can be produced by reacting acetic anhydride with aniline: [7]. C 6 H 5 NH 2 + (CH 3 CO) 2 O → C 6 H 5 NHCOCH 3 + CH 3 COOH. The preparation used to be a traditional experiment in introductory organic chemistry lab classes, [8] but it has now been widely replaced by the preparation of either paracetamol or aspirin, both of which teach the same practical techniques (especially ...
2,4,6-Trichloroaniline + 3 HCl The preparation of 2,4,6-trichloroaniline Safety Occupational exposure to 2,4,6-trichloroaniline may occur through inhalation and dermal contact with this compound at workplaces where 2,4,6-trichloroaniline is produced or used (SRC). The general population may be exposed to 2,4,6-trichloroaniline via drinking water and dermal contact with this compound in ...
Compared to aniline, the basicity of 2,4-dinitroaniline is even weaker. It is due to the electron-withdrawing nature of the nitro groups. This makes the pK a of conjugate acid of 2,4-dinitroaniline being even lower than that of hydronium ions, meaning that it is a strong acid. C 6 H 3 (NH + 3)(NO 2) 2 + H 2 O → C 6 H 3 (NH 2)(NO 2) 2 + H 3 O +
Amine. In chemistry, amines (/ ə ˈ m iː n, ˈ æ m iː n /, [1] [2] UK also / ˈ eɪ m iː n / [3]) are compounds and functional groups that contain a basic nitrogen atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3 (in which the bond angle between the nitrogen and hydrogen is 107°), wherein one or more hydrogen atoms have been replaced by a substituent such as an ...
