Write the structures and IUPAC names of the compounds with molecular formula, `C_(4)H_(8)O_(2)`.

Explanation

The molecular formula, `C_(4)H_(8)O_(2)` conforms to the general formula of monocarboxylic acids and esters. Therefore the following structures of monocarboxylic acids and esters can be written with the given formula :
Monocarboxylic acids:, `CH_(3)underset("Butanoic acid")(CH_(2))_(2)CO_(2)H underset(2 -"methylpropanoic acid")(CH_(3))_(2)CHCO_(2)H`
Estres: `underset("Methyl propanote")(CH_(3)CH_(2)COOH_(3)) , underset("Ethyl ethanote")((CH_(3))COOCH_(2)CH_(3)`
`underset("Propyl methanoate")(HCOOCH_(2)CH_(2)CH_(3)) , underset("Isopropyl methanoate")(HCOOCH(CH_(3))_(2)`
