Hi , I really need help on a simple question. Could someone please tell me, what functional groups are present in diazepam otherwise known as valium. Thank You!

I gave you this link in your last question:

Diazepam - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Diazepam)

You should have been able to look at the structure and see the functional groups.

The Carbonyl group (R2C=O) is a ketone. The N-R1R2R3 is an amine. The R1=N-R2 group is an imine and the R-Cl group is just a chloride. There is also an aromatic ring (Phenyl), but usually one doesn't usually think of them as a functional group.

Why all the interest in Valium?

I have a hugee assignment worth 30 % I need to get an 85 to pass , thanks a lot for all your help
