I see aryl and amide, due to presence of NH and C double bond O...

Mark scheme says ketone and amine, how come?

hmmm im thinking...because it's AS not A2, they expect u to only know ketones and amines as seperate functional groups. maybe theyre intentionally misleading u bc u havent learnt amides till u reach y13

A ketone is:
O
||
R-C-R'

"R group: An abbreviation for any group in which a carbon or hydrogen atom is attached to the rest of the molecule. Sometimes used more loosely, to include other elements such as halogens, oxygen, or nitrogen." - Your exam board obviously allows nitrogen to be considered as an R group.

Hence a the functional group ketone is found on the far right side of the molecule

the amine group is:

O
||
C-N-
.....|

An example of the amine group on the molecule is literally anywhere there is an N.

the C=O N- structure implies an amide, not an amine.... ^^

Hehe i know thalidomide from Breaking Bad im not even doing a level chem. thalidomide can help you sleep but its optical isomer can cause birth defects.

Whoops I misspelt it. Nightmare.

There can't be an amine group if it's got the C=O, all N has a C=O attached to it. So this means that the mark scheme is wrong no matter what. I assume it's not in the course specifications so they just want "amine" as you're not meant to know C=O means amide.
...H

R-N-R'
The groups would in fact be called "Imide"s due to presence of the 2 C=O groups but hey who cares.
