Question

classify each of the following organic compounds and circle the functional groups in their structures. a. hcooh b. ch₃con(ch₃)₂ c. ch₃nh₂

Explanation:

Step1: Identify $\ce{HCOOH}$

$\ce{HCOOH}$ has $\ce{-COOH}$ group, is carboxylic acid.

Step2: Identify $\ce{CH_3CON(CH_3)_2}$

$\ce{CH_3CON(CH_3)_2}$ has $\ce{-CONR_2}$ group, is amide.

Step3: Identify $\ce{CH_3NH_2}$

$\ce{CH_3NH_2}$ has $\ce{-NH_2}$ group, is amine.

Answer:

a. Carboxylic Acid; Functional - group: $\ce{-COOH}$ (circle the $\ce{-COOH}$ part in $\ce{HCOOH}$)
b. Amide; Functional - group: $\ce{-CONR_2}$ (circle the $\ce{-CON(CH_3)_2}$ part in $\ce{CH_3CON(CH_3)_2}$)
c. Amine; Functional - group: $\ce{-NH_2}$ (circle the $\ce{-NH_2}$ part in $\ce{CH_3NH_2}$)
