I found a video on YouTube about electrophilic aromatic substitution It is an analogy of this reaction and Homer Simpson and doughnuts. Hope this is helpful!

I have found a book by Karen Timberlake which looks really good. Has anyone taught from this book?

The reason the electron configuration is listed 3d10 4s2 4p6 is that they list the orbitals in numerical order, not by energy levels or filling order. This also helps newbies remember that the n = 3 shell consists of 3s, 3p, and 3d orbitals. Hope this helps!
