Count the open-chain structural isomers of molecular formula $C X_{4} H X_{8} O X_{2}$ that are either carboxylic acids or esters (structural isomers only, no stereoisomers).

Numerical answer type, tolerance 0.5.

Answer: 6

Carboxylic acids: butanoic acid and 2-methylpropanoic acid, 2 isomers. Esters: methyl propanoate, ethyl ethanoate, propyl methanoate and propan-2-yl methanoate, 4 isomers. The total is 2 + 4 = 6.
