question 8\nwhat is this functional group called?\namino\ncarboxyl\nketone\naldehyde\nhydroxyl
Answer
Brief Explanations:
The structure shown represents an oxygen - hydrogen bond characteristic of the hydroxyl functional group. An amino group has a nitrogen - hydrogen structure, a carboxyl group has a carbon - oxygen - oxygen - hydrogen structure, a ketone has a carbon - oxygen double - bond with carbon on both sides of the oxygen, and an aldehyde has a carbon - oxygen double - bond with a hydrogen on one side of the carbon.
Answer:
hydroxyl
