| Methane | CH 4 | * It is colorless and, in liquid, less dense than water * It is slightly soluble in water but very soluble in organic liquids such as gasoline, ether and alcohol | * is a type of gas. * There is a small amount of methane in the air you breathe. A methane molecule contains carbon and hydrogen atoms. | * Can be used as fuel burning and * gas is also called the swamps and Formenos | |
| Ethane | C 2 H 6 | * The is a gas at room temperature. * It has a higher octane index of gasoline and has a lower vapor pressure * Ethane is an excellent automotive fuel. | * The structure is unique in that there is only one way to unite the carbon atoms in these molecules * Not affected by strong acids or bases or by oxidants such as permanganate. | * Ethane can be used in two ways: As blended with gasoline with the aim of increasing the octane of gasoline. As pure ethane, ethane hydrated compound, to 95.5 GL. | |
| Propane | C 3 H 8 | * Hydrocarbon gas, colorless and fuel oil is in American. | * has low polarity. Unaffected by strong acids or bases or by oxidants such as permanganate. | * is a good substitute, the gas obtained by dry distillation of coal. * Serves as a fuel in homes | |
