benzene rings and ortho/meta/para-- need to know?

[sheldon09]

just wondering if we need to know ortha/meta/para directing groups, etc for the mcat. kaplan seems to bring this up in their FLs. But I've never seen it on AAMC.

I've heard its been removed from the mcat. any ideas?

thanks!

I've heard benzene reactions were removed awhile back as well, but the concept of which substituents are electron donating and which are electron withdrawing is very important for concepts like acidity/basicity as well as trends in reactivity for other reactions. So I'd still study it from this perspective. There was another post about this a few months back but I'm too lazy to dig it back up. You might search for it if you're still not satisfied.

You should be able to understand why a group would be ortho/para directing or not but you don't have to memorize which is which. I forgot if I ever came across that stuff but it's easy enough to know and the concept is applicable to other topics, as cool beans said.
