Rank the reactivity of the compounds shown below when using a Friedel Crafts alkylation reaction. Make sure you label which is least reactive and most reactive. (5 pts)
Rank each of the following compounds in decreasing order of reactivity towards Friedel-Crafts alkylation. Most reactive = 1; if a compound will not react, rank it as "non" rather than assigning a numerical value. Compound A: bromobenzene Compound B: aniline Compound C: anisole Compound D: iodobenzene

The rate of solvolysis of iodide 1 is 100 times faster than the rate of solvolysis of iodide 3. What explanation (with structures) can you provide for...
When performing a Friedel-Crafts alkylation reaction, not only does one have the problems of multiple alkylation and rearrangement of the cation, but the presence of strong electron donating groups(yes, donating is correct) prevents reaction. Provide an explanation for this. Metallocenes, like ferrocene cannot be nitrated. Why? Draw the structure of the diacetylferrocene you would obtain if ferrocene were diacetylated. Draw an arrow pushing mechanism for the formation of the acylium ion when acetic anhydride reacts with phosphoric acid. Provide the...
