SUMMARY

The total number of isomeric carboxylic acids and esters with the molecular formula C4H8O2 is confirmed to be 6. The identified isomers include 2-methyl propanoic acid, butanoic acid, methyl propanoate, ethyl ethanoate, propyl methanoate, and isopropyl acetate. The discussion highlights the importance of considering all structural variations, including those based on formic acid, to arrive at the correct total. Participants collaboratively verified the isomers, leading to the conclusion that option A is correct.
