A
Propane (C_3H_8)
B
Butane (C_4H_{10})
C
Methane (CH_4)
D
Ethane (C_2H_6)
Verified step by step guidance1
Understand that natural gas is a fossil fuel primarily composed of hydrocarbons, which are molecules made of hydrogen and carbon atoms.
Recall that the main components of natural gas are simple alkanes, which are saturated hydrocarbons with single bonds only.
Identify the given options: Propane (C\_3H\_8), Butane (C\_4H\_{10}), Methane (CH\_4), and Ethane (C\_2H\_6).
Recognize that methane (CH\_4) is the simplest alkane and is known to be the predominant component of natural gas, typically making up about 70-90% of its composition.
Conclude that among the options, methane (CH\_4) is the main component of natural gas due to its abundance and chemical properties.
