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.
