Hey Everybody, this is one of the tricks that organic chemistry profs always catch o-chem students on when doing EAS. Put a group in the meta position, when there is an ortho,para director already on the ring. For example:
How do you put a methyl group in the meta position in this problem? Here’s the trick: Start with a meta director on your ring, place the methyl group in the meta position, then change that meta director into an amine.
A nitro group is the logical choice for the “meta-switcheroo”….keep it in mind next time you run into a problem like this.
As always, we think organic chemistry help is a great resource for all of you organic chemistry needs.
