LESSON 3 – Text 1
Hydrocarbon
Hydrocarbons are compounds containing only carbon and hydrogen atoms. The
simplest hydrocarbon is methane, CH4. Its molecules are tetrahedral, the four
hydrogen atoms lying at the corners of a regular tetrahedron around the carbon
atom, and connected with the carbon atom with single bonds. Methane is a gas,
which occurs in natural gas, and is used as a fuel. It is also used in large quantities
for the manufacture of carbon black, by combustion with a limited supply of air. The
hydrogen burns to water, and the carbon is deposited as very finely divided carbon,
which finds extensive use as filler for rubber for automobile tires.
Methane is the first member of a series of hydrocarbons having the general formula
CnH2n+2, called the methane series or paraffin series. The compounds of this series
are not very reactive chemically. They occur in complex mixtures called petroleum.
The molecules heavier than ethane are characterized by containing carbon atoms
attached to one another by single bonds. The lighter members of the paraffin series
are gases, the intermediate members are liquids, and the heavier members are solid
or semi-solid substances. Gasoline is the heptane-nonane mixture, and kerosene
the decane-hexadecane mixture. Heavy fuel oil is a mixture of paraffins containing
twenty or more atoms per molecule. The lubricating oils and solid paraffin are
mixtures of still larger paraffin molecules.
