- Definition of C6H6
1.1 The common name of C6H6 is Benzen. This is an organic compound, belonging to a group of chemical compounds called hydrocarbons.
1.2 The English name of Benzen is Benzene.
1.3 The molecular mass of Benzene consists of 6 Carbon atoms and 6 Hydrogen atoms.
1.4 Each Carbon atom in Benzene has an atomic mass of 12 units, and each Hydrogen atom has an atomic mass of 1 unit. Therefore, the atomic mass of Benzene is 78 units.
1.5 The molecular structure of Benzene is a ring consisting of 6 Carbon atoms, connected by resonance between single and double bonds. The 6 Hydrogen atoms are connected to the 6 Carbon atoms to form a benzene ring.
1.6 Ion structure: Benzene does not form ions due to its lack of ionization ability.
- Properties
2.1 Physical properties of Benzene: Benzene is liquid at standard conditions, colorless, with a characteristic aroma, insoluble in water but soluble in organic solvents such as ethanol, ether. The PH of Benzene is 7, meaning it is neither acidic nor basic.
2.2 Chemical properties of Benzene: Benzene mainly participates in substitution, addition and reduction reactions, reacts poorly with acids, bases and halogens, but readily reacts with strong oxidizing agents such as KMnO4, K2Cr2O7.
- Common chemical equations
Reaction of benzene with bromine: C6H6 + Br2 -> C6H5Br + HBr
Reaction of benzene with nitric acid: C6H6 + HNO3 -> C6H5NO2 + H2O
- Synthesis of Benzene
4.1 Benzene synthesis in the laboratory often uses the method of reducing benzen diazonium with hydrogen.
4.2 Industrial synthesis of Benzene often uses the method of restructuring from other hydrocarbons such as toluene, xylene.
