Question

Identify the ester compound in the options given below.

• A. $C{H}_{3}C{H}_{2}COOC{H}_3$
• B. $C{H}_{3}C{H}_{2}COOH$
• C. $C{H}_{3}C{H}_{2}COC{H}_2$
• D. $C{H}_{3}OH$

Answer 1

The correct option is A

$C{H}_{3}C{H}_{2}COOC{H}_3$

Esters are compounds obtained from the reaction between carboxylic acid and alcohols. Ester compounds have the functional group $-COO$. Here the compound having functional group $-COO$ is $C{H}_{3}C{H}_{2}COOC{H}_3$. This compound is known as methyl ethanoate.

Compound $C{H}_{3}C{H}_{2}COOH$ belongs to the family of carboxylic acid as it has $-COOH$ functional group.

Compound $C{H}_{3}C{H}_{2}COC{H}_2$ belongs to the family of ketones as it has $-C=O$ functional group.

Compound $C{H}_{3}OH$ belongs to the family of alcohols as it has $-OH$ functional group.
