which book do u use?? I'm too sure abt this..since alcohol becomes alkyl.....it can't have a O single handedly....no not possible

check the diagram - http://filesmelt.com/downloader/ester.bmp
@nid - roger norris, roger stanbridge

maybe u guyz are confusing this reaction with a neutralization reaction, in that, the H from the acid is taken.

Na+(aq)+OH-1(aq)+H+(aq)+Cl-(aq) --> Na+(aq)+Cl-(aq)+H2O

dude...the reaction is perfect but as u have chosen H from the ethanol and OH from the acid...its wrong...it has to be te other way round...
as in H from the acid....nd OH from ethanol..
thee is no doubt about onfusing wid neutralisation reaction....bt  gotta understand dt be it neutralisation reaction or some other...an acid cannot give an OH-ion...

Ok.....I just revised some organic chemistry...and adi is right...it's the acid that give OH and alcohol that gives H

http://www.chemguide.co.uk/physical/catalysis/esterify.html

It's pretty complicated actually.......I haven't really started with organic chem in A level.....so to explain would be a problem........the mechanism explained in the site is pretty good....check it out

And for now evn if you don't get it....jst remember OH is from acid And H from alcohol
