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
The lightest element of all should have the lightest atomic mass. It is hydrogen-1 isotope. This atom has only one proton and no neutrons.
The lightest 'non-metal' could be Hydrogen and Helium! Both are gases, and therefore, not a metal.
The abbreviation for hydrocarbon is HC.
first you need to know that what is a hydrocarbon .A hydrocarbon is a covalent compound in which only carbon and hydrogen is present . Now you can see that in CH3-CH2OH a functional group OH i.e. alcohol. so you got your answer that H3C-CH2OH is a functionalized hydrocarbon.

The opposite of lightest is heaviest.
the lightest elements are gases and the lightest of these are hydrogen and helium.
The superlative form of the adjective 'light' is lightest.
The lightest metal is lithium.
Hydrogen is the lightest element. The isotope protium is the lightest kind of hydrogen atom.
ANSWER:The ant is the lightest animal in the world.
gas is the lightest in weight
No hydrogen is the lightest element.
The superlative for "light" is "lightest."
Hydrogen was, and is, the lightest gas
Iron 56 is the lightest
