Which hydrocarbon makes up the largest percentage of natural gas?

Explanation:
Natural gas is dominated by methane because it is the simplest and most stable hydrocarbon formed during the thermal breakdown of organic matter. Methane remains a gas under typical surface conditions, so it makes up the largest share of natural gas. The other hydrocarbons—ethane, propane, and butane—are heavier and occur in smaller amounts; they’re often removed or separated out as natural gas liquids or used as separate fuels. So the main component you’ll find in natural gas, in the greatest proportion, is methane.
