Hi guys,
           I am studying friedel-Crafts Acylation reaction mechanism and in our hands out they state the "for FC acylation reactions 1.1 molar eqs of AlCl3 must be used as ketones are slightly basic and form a salt with the product. Thus AlCl3 does not act as a catalyst in the acylation reaction."

I am unsure what "eqs" means, could someone care to explain the rest in quotation marks. I can see why a salt would be formed but unsure why they are specifiying a specific molar quantity.

My other question is in regards to the acidity of phenol.

In my handout it finishes with, because "pKa is directly proportional to the standard free energy of ionisation, phenols have lower pKa values and are thus more acidic than alcohols.

Could someone explain to me mathmatically how this occours? I do understand that phenols are more acidic than alcohols as a lone pair from the oxygen can be donated into the ring, making the Hydrogen more partially positive and more easily lost, hence more acid. I also understand if a compounds is more acidic than another compound then it will have a lower pKa but I am unsure how this relates to the standard free energy of ionisation.

thanks in advance!
