So alkyl, amine, alcohol groups and others are ortho/para directing groups on benzene because of the possible ressonance structures of the carbocation structures, as i understand it. However I don't see how to determine wether under the specific circumstances, the substituent will be mostly para or ortho. I guess ortho is the must obvious as it has two possible atoms too substitute on vs. only one para atom, but this dosen't always seem to be the case?
maybe somebody has a link to a place with info about the exact location of the substitution group, in para/ortho directing cases?:)
