QUESTION

# Which of the following is the main constituent of natural gas?${\text{A}}{\text{.}}$ Methane${\text{B}}{\text{.}}$ Ethane${\text{C}}{\text{.}}$ Propane${\text{D}}{\text{.}}$ Butane

Methane is a colourless, odourless gas that occurs abundantly in nature and as a product of certain human activities. Methane is the simplest member of the paraffin series of hydrocarbons and is among the most potent of the greenhouse gases. Its chemical formula is ${\text{C}}{{\text{H}}_4}$.
Ethane is a colourless, odourless, gaseous hydrocarbon (compound of hydrogen and carbon), belonging to the paraffin series. Its chemical formula is ${{\text{C}}_2}{{\text{H}}_6}$.
Propane is a colourless, easily liquefied, gaseous hydrocarbon (compound of carbon and hydrogen), the third member of the paraffin series following methane and ethane. The chemical formula for propane is ${{\text{C}}_3}{{\text{H}}_8}$.
Butane is either of two colourless, odourless, gaseous hydrocarbons (compounds of carbon and hydrogen), members of the series of paraffinic hydrocarbons. Their chemical formula is ${{\text{C}}_4}{{\text{H}}_{10}}$.
