C2H5OH
The end (-anol) tells you it's an alcohol, which means it has an OH group somewhere. The begining (eth-) is the prefix used in organic chemistry to mean two, which tells you there are two carbons. The two carbons are bonded to each other (that's just how alcohols work, because of the electronegativities of the atoms), and each one can bond to three other things. If it were an alkane (the simple ones that are just a carbon chain surrounded by the maximum possible hydrogen atoms), it would be two carbons with six hydrogens around it (which is called ethane), but since it's an alcohol, there has to be an OH group somewhere, which is added basically by sticking an oxygen between one of the carbon-hydrogen bonds in the alkane. That leaves you with two carbon atoms, six hydrogen atoms, and one oxygen atom, giving a molecular forumla of C2H6O. But because the OH is basically one thing, it's generally written like that is a single atom, so the molecular forumla for ethanol is given as C2H5OH.

C2H6O, variously represented as EtOH, C2H5OH or as its empirical formula C2H6O.
