Which of the following statements is incorrect description of electrophiles? Question 1 options: Electrophiles contain large electron density. Combination of nitric acid and sulfuric acid can generate a strong electrophile. Electrophiles lack electron density. Electrophiles are attracted to negatively charged atoms. Question 2 (1 point) 3-Nitro methyl benzoate is more reactive toward electrophilic aromatic substitution reactions than methyl benzoate. Question 2 options: True False Question 3 (1 point) Predict the carbon atom that carries greatest partial negative charge.

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...

Substituents on an aromatic ring can have several effects on
electrophilic aromatic substitution reactions. Substituents can
activate or deactivate the ring to substitution, donate or withdraw
electrons inductively, donate or withdraw electrons through
resonance, and direct substitution either to the ortho/para or to
the meta positions. From the following lists, select the
substituents that have the indicated property. The substituents are
written as -XY, where X is the atom directly bound to the aromatic
ring.
