The question lies in the picture below, my first question is, can groups other than alkyl/hyride shift as well like this in the picture? it's not too large?
And if they can, why wouldn't the benzene ring shift instead since it's the smallest.
the teacher said the first product would happen but why? the carbocation wouldn't be as stable because NO2 is electron withdrawing and it would make the carbocation less stable...
Any explanation?
