Final answer:
Aldehydes and ketones are identified as the two organic functional groups referenced in Model 1, both containing a carbonyl group with a carbon-oxygen double bond.
Step-by-step explanation:
Referring to Model 1, the two identified organic functional groups are aldehydes and ketones. Both groups feature a significant functional group known as the carbonyl group, characterized by a carbon-oxygen double bond.
The distinction between them lies in the placement of this carbonyl carbon: In aldehydes, the carbonyl carbon is bonded to at least one hydrogen and another carbon, while in ketones, it is bonded to two carbon groups.
These functional groups are distinct from others such as alkanes, which only have carbon-carbon and carbon-hydrogen single bonds, and from alcohols and amines, which have different structural features and properties.
