fiedel crafts always gave me problems thanks khan!

i love in it

how to know which reaction occured first?

Thank you BUT how do we know the orders

couldn't the acylation have occurred last in the 2nd example?

it is para to br and meta to no2...

Thanks dr Jay

For the second one, couldn't you nitrate second, then use reduction (such as Zn(Hg) HCl) to make it NH2 for an ortho/para directing then use friedal crafts third? You would have an extra step converting back to NO2 with MCPBA but is that also possible???

Tnx

Thank you for this

W video.

Is there any kind of blanket or general rule that tells us in what order to install groups onto the ring?
