For 1,1,4,4-tetramethyl-1,2,3,4-tetrahydronaphthalene:
What would be the products following a standard nitration with $\ce{NO2+}$?
Since the substituent group is alkyl then it is ortho- or para- directing. But surely there are steric hindrance factors to be considered due to the bulk of the ring which would mean para- is favoured instead of ortho. However, when I try to draw out the structure it seems the arrows are meta- instead!
