toluene is a common name-The IUPAC name for toluene is methylbenzene.he use of this trivial form (acetate for ethanoic acid in general) is so common that this is called a retained IUPAC name.
Best Answer: The correct IUPAC name for this compound is methyl propanoate. This is an ester The reaction of propanoic acid CH3CH2COOH and methanol CH3OH can form this ester.From the IUPAC rules, the ester will take its first name from the prefix of the alcohol, in this case methyl, and the second name from the acid,propanoic acid, which gives the name propanoate.Thus CH3CH2COOCH3 is named methyl propanoate by the rules laid down for IUPAC nomenclature for esters.est Answer: The correct IUPAC name for this compound is methyl propanoate. This is an ester The reaction of propanoic acid CH3CH2COOH and methanol CH3OH can form this ester.
