Hi everyone, I'm new to this forum  .
I'm currently doing a project on Nandrolone and I have to draw the structure of it and also highlight the functional groups.

I'd be very greatful if anyone can outline these functional groups for me?(with the aid of a diagram would be really helpful).

Oh, and the reaction between Nandrolone and Bromine would be great as well.
Thanks in advance for any help.

In my opinion, the C=O group (with an adiacent C=C, which can produce keto-enol tautomer) and the beta-OH group are the ones that need to be highlighted.

I am not to give you the detailed mechanism: that's up to you (it is extremely easy).

I just want to tell something about this reaction: as you see, you get one product...but keeping this solution, which contains Br2 and CCl4, after approximately 5 days you'll find a mixture (85% vs. 15%) of the two isomers (4alpha-5beta 85%, 4beta-5alpha 15%).
