All right, we've got this system of benzene rings a and b.
00:07
Oops.
00:12
I'm not drawing well today.
00:14
Okay.
00:16
And one has a nitro group on it.
00:21
And then it's attached to a ch2.
00:25
And that ch2 is attached to another benzene ring.
00:34
All right.
00:35
And the question is, if we attempt to make this undergo some sort of friddle crafts, asylation, so i'll just, it's not super important, but that would be adding some sort of acid chloride with either iron chloride or aluminum chloride.
00:56
It's a catalyst.
00:57
I think it's usually aluminum chloride, though.
01:00
It's more common.
01:01
So let's put that.
01:04
Where would this r group add? or where would this acid chloride at? and the way we're going to figure this out is that recall that nitro groups are, well, any substituent on a benzene ring is either electron withdrawing, an electron withdrawing group, or an electron donating group.
01:27
Right.
01:27
So that's what this question is about.
01:28
And i will just say right off the bat that, and i'll go into this a bit more depth, nitro groups are electron withdrawing.
01:37
Alkal groups are electron donating.
01:40
And electron donating groups activate benzene rings.
01:44
Electron withdrawing groups deactivate benzine rings.
01:51
So this ring on the left is being both activated and deactivated.
01:58
The ring on the right is just being activated.
02:01
So the one on the right is more likely to undergo electrophilic aromatic substitution...
