Question

Which functional group does the molecule below contain? HIC H H=COH [

Answer 1

Answer:

$D. \ \ \ \text{hydroxyl}$

Explanation:

Alcohols are organic compounds that are composed of the hydroxyl function group ($-\text{OH}$), bonded to a carbon atom of an alkyl or a substituted alkyl group. Hence, the functional group of alcohols is the hydroxyl group ($-\text{OH}$).

According to the International Union of Pure and Applied Chemistry (IUPAC) nomenclature, alcohols are named by changing the -e ending of the name of the parent alkane to the suffix -ol.

For example, the alcohol molecule in the figure demonstrates a hydroxyl group bonded to a methyl group. Therefore, the name of the alcohol is methanol.
