Hydrocarbon

C6H6-C6H6-NO2

Maybe it is not the best way to write it but I suppose you know what I mean. This is a molecule which consists one benzene and one nitrobenzene conected to each other.

a) What is it's name?
b) How to produce it (having benzene)?

Thanks in advance for your help

Count your hydrogens!  It should be C6H5-C6H4NO2

No it shouldn't! There are two benzenes conected by a single bond and there is NO2 conected to one of them

The file you posted is corrupted.  I assume it had a picture like this.

I see, you're right. Sorry...

Anyway, how to produce it having benzene?
I know how to nitrate benzene but how to conect two benzenes?

What ways have you learned to make a carbon-carbon bond from benzene or a benzene derivative?   There are several ways to do this, but I'm guessing you have only learned one or two.

I learned to add HNO3 and H2SO4 to C6H6 and we get C6H5NO2 + H2O

I said I know how to make a nitrobenzene but I don't know how to make that one...

But do you know any ways of making a carbon-carbon bond off of a benzene ring?

If I knew, I wouldn't ask :D

You must have learned some way if they are asking this question!

How about an Ullman reaction?

Or maybe a nucleophilic aromatic substitution using phenyllithium?

You have to be a little careful with lithium carbanions and nitro groups, sometimes they add directly to the nitro instead of in a conjugate addition type of way.

But SNAr is a great idea!  I hadn't thought of that.
