Bromination of 4-hydroxybenzaldehyde
« on: November 16, 2008, 11:56:50 PM »
The OH group is para to the CHO group on the benzene ring.  Adding Br2  would produce a Bromine bond ortho or meta to the hydroxyl group? Or would it be a mixture of both, with which one being more abundent?  Assuming it's at room temp.

I'm having huge troubles with this.  Any help would be greatly appreciated!

Are OH groups ortho/para directing, or meta deactivating?
Is an aldehyde ortho/para directing or meta deactivating?
