Two carboxylic acids have the formula $C_{4} H_{8} O_{2}$ $"C"_4"H"_8"O"_2$ .

Explanation:

We can rewrite the formula as $C_{3} H_{7} COOH$ $"C"_3"H"_7"COOH"$ .

$C_{3} H_{7}$ $"C"_3"H"_7$ is a propyl group.

We can put the $COOH$ $"COOH"$ group on the end of the propyl chain to get ${CH}_{3} {CH}_{2} {CH}_{2} COOH$ $"CH"_3"CH"_2"CH"_2"COOH"$ , butanoic acid.

Or we can put the $COOH$ $"COOH"$ group in the middle of the propyl chain to get ${({CH}_{3})}_{2} CHCOOH$ $("CH"_3)_2"CHCOOH"$ , 2-methylpropanoic acid.
