Some Useful Alkane

Methane is found in swamps and marshy lands where it is produced by bacterial decomposition of complex vegetables and animal matters. It is also found in coalmines. This note provides an information on different types of alkane and their uses.

Summary

Methane is found in swamps and marshy lands where it is produced by bacterial decomposition of complex vegetables and animal matters. It is also found in coalmines. This note provides an information on different types of alkane and their uses.

Things to Remember

  • Methane is found in swamps and marshy lands where it is produced by bacterial decomposition of complex vegetables and animal matters. It is also found in coalmines. 
  • Methane is used for manufacturing of water gas and hydrogen, making carbon black which is needed for paint and in rubber industry, making printing ink, and use in a form of LPG in domestic use, etc.
  • The molecular formula of ethane is C2H6.
  • Ethane occurs with methane in natural gas, coal gas, etc. It is also found in petroleum mines. It is slightly heavier than methane because its molecular weight is more than that of methane. It is use as gaseous fuel with methene, use for making other organic compounds,
  • The molecular formula of propane is C3H6.
  • Propane is found in oil refinery gas, natural gas and LPG (Liquefied Petroleum Gas). It is used as fuel and refrigerant and make other type of compounds.
  • The molecular formula of butane is C4H10.
  • Butane occurs as natural gas and is found in petroleum mines. It is used as fuel and also used in the manufacture of synthetic rubber. It is used as fuel and also used in the manufacture of synthetic rubber.

Some Useful Alkane

Some Useful Alkane

1. Methane:

Molecular formula: CH4

Structural formula:

http://upload.wikimedia.org/wikipedia/commons/c/c0/Methane-2D-square.png

Occurrence:

It is found in swamps and marshy lands where it is produced by bacterial decomposition of complex vegetables and animal matters. It is also found in coalmines.

Uses:

  1. It is used as a gaseous fuel in industries and household works since it produces a large amount of heat on burning.

4.It is used for making printing ink.

5.It is used in the form of LPG in domestic use.

2. Ethane

Molecular formula: C2H6

Structural formula:

http://upload.wikimedia.org/wikipedia/commons/9/99/Ethane-flat.png

Condensed formula: CH3CH3

Occurrence:

It occurs with methane in natural gas, coal gas, etc. It is also found in petroleum mines. It is slightly heavier than methane because its molecular weight is more than that of methane.

Uses:

  1. It is used as gaseous fuel along with methane.
  2. It is used for making other organic compounds.

3. Propane

Molecular formula: C3H8

Structural formula:
