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!
