what functional group is represented here? a amine b amide c alcohol d ketone
Answer
Brief Explanations:
An amide functional - group has the general formula R - CO - NR'R'', where R, R', and R'' can be hydrogen or alkyl groups. In the given structure, there is a carbon - oxygen double bond (C=O) bonded to a nitrogen atom (N) which has two methyl groups attached to it. This matches the structure of an amide. An amine has the general formula R - NH₂, R₂NH, or R₃N (no C=O adjacent to N). An alcohol has an - OH group. A ketone has the general formula R - CO - R'.
Answer:
B. amide
