OK i think it is the field that causes the pi electrons to circulate to begin with..so whether it opposes or adds to external field is just the right hand rule then.. is that correct understanding?

is it the actual external mag field that causes the circulation to begin with? If it does then I think I am starting to understand, but if not then I think I am more confused. please answer again, thanks

Why do we assume that the circulating pi electrons induces another magnetic field, B_in, that adds to the external mag field, B_ext, instead of opposing B_ext? Couldnt the pi electrons just as easily oppose B_ext? This lecture says the protons on benzene will experience greater effectual...

ok ill try chemddodle again..i gave up because of the numbering problem i was having.. btw I am talking about the online chemdoodle widget thing not the download software

I mean what is the most common way people do this? I was using something called chemdoodle but i couldn't figure out how to number the atoms. Is chemdoodle the best or something better? thanks

please ignore that little grey dot above the ring.. no idea what that is (just learning chemdoodle).. thanks

Sorry not sure why i said ortho, yup i definitely meant para..heres drawing so its clear

How many NMR signals and peaks will there be for a di-substituted benzene ring and why? The ring has one CH3 and and a Cl ortho to the CH3. (This isn't a homework problem but I am running into same issue whenever I encounter rings wrt NMR) i am specifically confused as to how to apply...
