what are the chemical and physical properties of benzene?
113173
Benzene has a boiling point of 80.1 °C (176.2 °F) and a melting point of 5.5 °C (41.9 °F), and it is freely soluble in organic solvents, but only slightly soluble in water.

The important chemical properties of organic compounds are Combustion: Carbon in all its allotropic forms burns in air or oxygen to give carbon dioxide and releases energy in the form of heat and light. Most carbon compound also release a large amount of heat and light on burning.

The usual structural representation for benzene is a six carbon ring (represented by a hexagon) which includes three double bonds. Each of the carbons represented by a corner is also bonded to one other atom. In benzene itself, these atoms are hydrogens.

Color, odor, density, melting temperature, boiling temperature, and solubility are examples of physical properties. Physical properties can be used to identify a pure substance.
1369164
Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change. To identify a chemical property, we look for a chemical change.

Characteristics such as melting point, boiling point, density, solubility, color, odor, etc. are physical properties. ... Reactions of a substance, either with itself or with another substance are chemical properties. Physical and chemical properties can be used to classify a substance as ionic or molecular.

Classifying how a substance looks and how it smells does not require changing its composition. Thus, nitrogen's lack of color and odor are physical properties. Some other examples of physical properties are viscosity, density, melting point, volume, and ductility.
