Question

Discuss the physical properties of carbon.

Answer 1

• Carbon is a non-metal found in various allotropic forms from soft powder to hard solid.

• All the allotropic forms of carbon are solids whereas its compounds exist in solid, liquid and gaseous state.

• Amorphous forms of carbon and graphite are almost black in colour and opaque. Diamonds are transparent and shiny.

• Its amorphous forms have low melting and boiling point compared to crystalline forms.

• Carbon is insoluble in water and other common solvents. But some of its compounds are soluble in water and other solvents.

E.g Ethanol and $C{O}_2$are soluble in water.
