Chemistry of Carbon and Hydrocarbons

Study Notes

Carbon

Carbon is a non-metal element with atomic number 6, symbol C, and atomic weight 12.011.
It's tetravalent, meaning it forms four covalent bonds.
Carbon exhibits allotropy, existing in various forms such as diamond, graphite, and fullerenes.
Diamond is a highly hard, transparent crystalline structure with a strong covalent network.
Graphite is a soft, black, slippery material with a layered structure.
Fullerenes are cage-like structures, such as buckminsterfullerene (C60).
Carbon plays a vital role in organic chemistry.
Carbon forms the backbone of most organic molecules.
Carbon's ability to form strong covalent bonds with other elements allows for a vast diversity of organic molecules.

Hydrocarbon

Hydrocarbons are organic compounds composed solely of carbon and hydrogen atoms.
They are the simplest type of organic molecule.
Hydrocarbons are classified based on the types of bonds between carbon atoms.
Alkanes have only single bonds between carbon atoms.
Alkenes contain at least one carbon-carbon double bond.
Alkynes contain at least one carbon-carbon triple bond.
Aromatic hydrocarbons have a cyclic structure with alternating double bonds (e.g., benzene).
Hydrocarbons are primarily derived from fossil fuels, which are finite resources.
They are used as fuels, solvents, and raw materials for the production of other chemicals.
Combustion of hydrocarbons produces carbon dioxide and water, releasing energy.
Different types of hydrocarbons produce different amounts of energy during combustion.
Isomers are molecules with the same molecular formula but different structural arrangements.
Isomers of hydrocarbons have similar chemical properties but slightly different physical properties.
Alkanes are generally saturated hydrocarbons, meaning all carbon atoms are bonded to the maximum number of hydrogen atoms possible. Alkenes are unsaturated, meaning they contain at least one double bond, and alkynes, even more so, with their triple bonds.
The isomeric forms of hydrocarbons impact their properties and applications.
The branching of carbon chains affects the boiling points and melting points of hydrocarbons.
Longer carbon chains tend to have higher boiling points.
Cyclic hydrocarbons form closed ring structures, with properties affected by ring size and other structural aspects.
Hydrocarbons can be classified as aliphatic (straight chains, branched chains, and cyclic structures) or aromatic (benzene and similar structures with alternating double bonds).
