CH3-CH2-OH is more precise, since it tells you how the atoms are grouped. But both ways are right. 
Except that the sizes aren't right, of course.

Yes, and in case somebody needs a visualisation:

Actually, "C2-H5-OH" is wrong. Empirically it's C2H6O (only with the numbers as subscripts which I can't do here), and as Flop pointed out, CH3-CH2-OH gives the structure, distinguishing it from, say, CH3-O-CH3 which I believe can exist (it's been a while since I did any chemistry). EDIT: Yup, it's dimethyl ether - empirically the same as ethanol but chemically quite different.
The distinction is much more important with more complex molecules - even the next simplest alcohol has two diferent forms, CH3-CH2-CH2-OH and CH3-CH(OH)-CH2-CH3

But would CH3-O-CH3 still be a type of alcohol? I always thought an alcohol needs to have at least one OH group somewhere?

Nope, it's dimethyl ether - you're right, alcohols have at least one OH on them. It's got the same empirical formula as ethanol though.

And why would you want to burn something?

Ethanol's pretty flammable - I managed to set fire to a table in biology once with that stuff. More fun than just boiling a leaf, though

I'm so very, very, very, very sorry for not being able to post on the right day, but happy birthday, Kosta (my parents took my computer away for a week on the grounds that I didn't do my homework, before realising that it was a rubbish idea).
I hope you had a good one!
