For 10 points, name this prominent component of natural gas, the simplest alkane with a chemical formula of CH4.
Arndt-Eistert Synthesis reacts activated carboxylic acids with the diazo- variety of this molecule. This compound binds to a halogen radical in a common example of a free radical chain reaction. When its analogous functional group bonds to benzene, the result is toluene, and chloroform results in three chlorine atoms replacing three of its hydrogen atoms.
