Panda asked: I’ve been given an example of a reaction where benzene reacts with 1-chloro-2-methylpropane and aluminum chloride and I’m a little bit shaky on the outcome. When trying the question my results have been a benzene ring with a methylpropane attached plus HCl, however I’m told there might be other products? Am I on [...]
