WebSN1 is out. And so you might think that you can't do a nucleophilic aromatic substitution. But as a matter of fact you can, and let's take a look at the criteria in order to do so. So your ring must have an electron withdrawing group, so withdrawing some electron density from the ring. We have that here, of course. 82 collector corvette WebStudy with Quizlet and memorize flashcards containing terms like Compound A and compound B are constitutional isomers with molecular formula C3H7Cl.
