Please may someone explain how hydroquinone plus ammonium ethanoate forms paracetamol and water. What is the mechanism for this ? Thank you in advance.

Question 8.6
The question does not require you to know the reaction mechanism. But rather, the question is asking you if you can deduce the structure of ammonium ethanoate (CH3COO-NH4+), and then balance the equation by spotting that the product side is missing 2 oxygen and 4 hydrogen. Which you can guess as 2 water.
This is not the response you wanted, but it is a 1 mark question, and it will take a lot of time if you decided to find the reaction mechanism.
I can try to start it off, by using that phenol is a weak acid, so can dissociate to O- and H+.
The H+ associates with CH3COO- and O- (attached to benzene) associates with NH4+?
Then I get stuck.

Ahhh so it was just a balancing sort of question! Thank you so much that makes more sense !
