In friedel-crafts acylation experiment, Add acyl chloride, aluminium chloride and benzene in dichloromethane as a solvent. And stir and reflux at 40 degree. why reflux them at 40 degree?
Homework Answers
Friedel craft Acylation of benzene is an important reaction of organic chemistry. It is an electrophilic aromatic substitution reaction. In the procedure of this reaction refluxing is used. Refluxing the mixture at 40 degrees to provide the energy to the reactions for a longer time.

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...

Friedel-Crafts acylation followed by reduction is a convenient way to synthesize straight-chain alkylbenzenes. Why does the reaction of benzene with 1-chlorobutane and aluminum chloride give predominantly 2-phenylbutane as opposed to 1-phenylbutane? Why is the heat of hydrogenation of trans-1, 3-pentadiene less than the heat of hydrogenation of 1, 4-pentadiene?

I performed a Friedel-Crafts acylation with toluene and benzoyl
chloride as the reactants and aluminum chloride as the catalyst.
The product was expected to be a mixture of para- and ortho-isomers
of methylbenzophenone. This is the IR spectrum of the product that
I obtained. I am trying to figure out if I obtained
methylbenzophenone based on this spectrum. Please be detailed as to
why it is or is not methylbenzophenone and if not, what else it
could be! Thanks!
