2. This is an alcohol group attached to a two carbon skeleton.
This will be an important group used in the next lesson where it is involved

Note: All alcohols are poisonous to humans. The human liver can just
tolerate ethanol a little more than the other alcohols. Another name for
ethanol is vodka, beer, wine, etc. They all contain ethanol.
