- Please explain the answer Chlorine is an CIRCLE one ortho-para or meta director. Please include, show all resonance contributors after chlorobenzene loses aromaticity to form a sigma complex. To save time: If your answer is “ortho-para” director, just show addition at either position. If your answer is “meta” director, just show the result of meta addition.Examine the molecules below. Which site is most basic? Which H is most acidic? Highlight this site. Highlight this H. H :S- H. :O:Draw the sigma complex for the formation of the bromonium electrophile with proper resonance forms for the meta bromination of toluene and for the para bromination of toluene. Which resonance structure places the (+) next to the methyl group? Will either one (i.e. para and meta sigma complex) yield a fourth resonance structure? Given that alkyl groups such as CH3 are electron rich (i.e. no attached electronegative atoms), which sigma complex in part (A) would be more stable?

- Complete the generic mechanism for an electrophilic aromatic substitution (EAS) reaction using E as the electrophile, and show how the sigma complex is resonance stabilized. Use curved arrows to show the mechanism and the conversion between resonance structures. Make sure to add any missing charges. Note the use of a generic base (B) in the last step. Then, label the reaction coordinate diagram for a typical EAS reaction by correctly placing the structures on the diagram. Step 1: add a curved arrow.
