I am learning the nomenclature of esters and found that ethyl acetate was classified on Wikipedia to be the compound's IUPAC name while 'Ethyl ethanoate' is the compounds "Systematic name". Is this a typo? I thought ethyl acetate is just a common name while Ethyl ethanoate is the IUPAC name.

Also, can someone explain to me the difference between IUPAC and Systematic name on Wikipedia? http://en.wikipedia.org/wiki/Ethyl_acetate

Thank you so much.

Well acetic acid is not a systematic name. Its ethanoic acid so thats why its ethyl ethanoate. But IUPAC names arent always systematic but I would say the most common (ie. everyone uses acetic acid not ethanoic acid etc..)

Acetyl, acetic and acetate are all IUPAC.

Ethanoyl, ethanoic and ethanoate are the equivalent systematic names. I was taught these in high school, but beyond that level nobody uses them.
