Question

Name the functional groups present in the following compounds.

(i) CH₂−CO−CH₂2−CH₂−CH₂−CH₃
(ii) CH₃−CH₂−CH₂−COOH
(iii) CH₃−CH₂−CH₂−CH₂−CHO
(iv) CH₃−CH₂−OH

Answer 1

The functional groups for the given compounds are a ketone (CO), a carboxylic acid (-COOH), an aldehyde (-CHO), and an alcohol (-OH) group.

Step-by-step explanation:

The question is about identifying the functional groups present in a set of organic compounds. Here are the functional groups in the given compounds:

(i) CH₂-CO-CH₂-CH₂-CH₂-CH₃ - This compound has a ketone (CO) group.

(ii) CH₃-CH₂-CH₂-COOH - This compound contains a carboxylic acid (-COOH) group.

(iii) CH₃-CH₂-CH₂-CH₂-CHO - This compound features an aldehyde (-CHO) group.

(iv) CH₃-CH₂-OH - This molecule includes an alcohol (-OH) group.

Functional groups like ketones, carboxylic acids, aldehydes, and alcohols define the chemical characteristics and functions of organic molecules. Recognizing these groups helps in understanding molecular reactivity and properties.
