A science centre is preparing a particle model for an exhibit about the family containing most of the hydrocarbons in crude oil. The available models represent methane, an alkene, carbon dioxide and a polymer.
Which statement about the model choice is correct?
The methane model should be used because methane belongs to the alkane family.
The polymer model should be used because polymers are a major hydrocarbon family in crude oil.
The carbon dioxide model should be used because every carbon compound is a hydrocarbon.
The alkene model should be used because cracking produces alkenes from crude oil.
