Phenol: This is also known as hydroxybenzene and has a hydroxyl group (-OH) attached to one of the carbon atoms in the benzene ring. Phenol is used in the production of plastics, detergents, and pharmaceuticals. Aniline: This is also known as aminobenzene and has an amino group (-NH2)...
substituted and para-substituted benzene (substituents: NMe2, NHMe, NH2, NHOH, OH, OMe, Br, Cl, F, Me, CCH, CF3, CONH2, COMe, CHO, NO2, NO, and CN) have been performed at the density functional theory level by using Becke hybrid B3LYP functional with 6-311++G(d,p) basis ...
Its basic structure consists of an amino group (NH2) and a chlorobenzenesulfonic acid group (C6H4ClSO3H), which are attached to a benzene ring. This compound is soluble in water and has a melting point of approximately 220-225°C. It is also stable under normal conditions. Applicable ...
- Reaction: Benzene is treated with a mixture of concentrated nitric acid (HNO3) and concentrated sulfuric acid (H2SO4).- Process: The nitric acid generates the nitronium ion (NO2+), which acts as the electrophile. The benzene ring undergoes electrophilic substitution, resulting in the ...
