Ethene may not be the smallest what about ethyne? Ethene, ethylene, is C2H4 Unsaturated hydrocarbon molecules contain double or triple bonds. The smallest will either be ethene C2H4 with one double bond, or ethyne , acetylene, HCCH with one triple bond. Ethyne wins, it has 2 less hydrogen atoms making it the LIGHTEST. Look at the structures in wikipedia and work out which is physically the smallest. I still go with ethyne. Wikipedia Ethene Wikipedia Ethyne
Hydrocarbon is a carbon dioxide but is also call hydrocarbon
functionalized hydrocarbon
The 4H is the lightest pencil.
because methane is a hydrocarbon!
