Question 10 Why does nitrobenzene fail to undergo Friedel-Crafts alkylation with tert-butyl chloride and AICI! a. nitrobenzene is a poor nucleophile b. the nitro group is a strong electron donating group C. nitrobenzene reacts with AlCl3 d. the tert-butyl cation is a poor electrophile ) This response

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...

Friedel-Crafts Acylation of Ferrocene "riedel-Crafts reactions are examples of electrophilic aromatic substitution reactions. The eaction involves the substitution of hydrogen on the aromatic ring system by an electrophilic arbon species forming a new carbon-carbon bond. Friedel-Crafts reactions may be used to ntroduce either an alkyl or acyl group. Ferrocene does not undergo addition reactions typical of cyclopentadiene, but undergoes Electrophilic aromatic substitution. The Friedel-Crafts acylation reaction of ferrocene involves he addition of the acylium cation to one of the carbon...

Question 30 (4 points) Friedel-Crafts alkylation reactions cannot be performed on benzaldehyde because: The aldehyde group is strongly activating, and multiple substitutions occur on the aromatic ring. The aldehyde group gets alkylated instead of the aromatic ring. The aldehyde group attacks the Lewis acid to form an acid-base complex in which the aromatic ring is strongly deactivated The aldehyde group is moderately deactivating preventing any substitution on the aromatic ring. Question 31 (4 points) Which of the following produces no...

Friedel-Crafts acylation reactions cannot be performed on aniline because: The amino group attacks the Lewis acid to form an acid-base complex in which the aromatic ring is strongly deactivated. The amino group is strongly activating and multiple substitutions occur on the aromatic ring. The amino group is strongly deactivating preventing any substitution on the aromatic ring.
