Question

Draw all possible carboxylic acids and esters for a compound with molecular formula $C_{4} H_{8} O_{2}$ . Write the IUPAC name also.

Accepted Answer

The structural formulas for possible esters are:

(a) Ethyl acetate ( ${CH}_{3} {COOCH}_{2} {CH}_{3}$ )

When this ester is heated in the presence of sodium hydroxide solution, it changes into an alcohol and a carboxylic acid

(b) Propyl formate $({HCOOCH}_{2} {CH}_{2} {CH}_{3})$

(c) Isopropyl formate ( $HCOOCH ({CH}_{3})_{2}$ )

(d) Methyl propionate( ${CH}_{3} {CH}_{2} {COOCH}_{3}$ )

The structural formulas for possible carboxylic acids are:

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

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