3.3 carbon compounds

Purecarbons forms/allotopes: diamond-, graphite- and fullerenestructure.

Characteristics of diamond: hardest element

Characteristics of graphite: very wet, conducts electricity,

Use of graphite: used as lubricant for machines, and "graphite" in graphitepencils/pencils.

Carbon in diamond: In diamond, each carbon atom is bonded to four other carbon atoms, forming a rigid structure that makes diamond very hard.

Carbon in graphite: the c-atoms are in a flake, sabled ontop on eachother. Each c-atom is bonded with strong convalent bonds. Between each flake is weak bonds.

Carbon in fullerene: (e.g. buckminsterfullerene), carbon atoms are bonded to three other C atoms in a soccer ball shaped molecule. The bonds between the molecules are weak, so fullerenes can dissolve and form solutions.

Inorganic carbon compounds (slide 6): H₂CO₃ - contains a C-H bond (carbon),  in aquenous solution -> it dissociates into H⁺ and CN^- ions (the cyanide ion is inorganic). HCN is (normally) classed as inorganic, however Hydrogen cyanide is considered a borderline chemical compound.

What are carbonatom organic compounds groups: hydrocarbon, alcohol, and carbonacids
