Question

name the functional group shown in each molecule below. the first answer has been filled in for you.

molecule	functional group
ho — c(=o) — ch₃
ch₃ — ch₂ — o — c(=o) — ch₃
ch₃ — ch = ch₂

Explanation:

Step1: Identify functional - group in $HO - C(=O)-CH_3$

The $-COOH$ group is present, which is a carboxylic acid.

Step2: Identify functional - group in $CH_3 - CH_2 - O - C(=O)-CH_3$

It has an $-COO -$ group, which is an ester.

Step3: Identify functional - group in $CH_3 - CH=CH_2$

It has a carbon - carbon double bond, which is an alkene.

Answer:

Carboxylic acid
Ester
Alkene
