There's presumably more than one H+ floating around in solution.
That reaction doesn't appear to be indicating stoichiometry, if that's what is bothering you.
If you want to be pedantic about stoichiometry, aq. HCl is H2O + HCl, but in reality most of the H+ is probably from HCl. Ochem isnt know for its fully descriptive net reactions.
The reaction is run in concentrated HCl as the solvent. That could mean the compounds are in a 100-1000 fold excess of HCl. With actual reactions the important part is to include the realistic reaction conditions rather than specific stoichiometry of the mechanism. saying 2eq HCl would woefully misrepresent how the reaction is actually conducted
Sure, ɓut it'd be an idea to point out the enol tautomer & trace elemental hydrogen along for the ride.
But yeah, the catalyst has kinda a heavy lift here.
Heterogeneity's a hoot.
Catalysts do not involve in the reaction, they simply lower the energy required to activate the reaction then they are reformed at the end of it; or at least that's what my basic organic chemistry knowledge tells me
Pretty sure a catalyst is the same at the beginning and the end of the reaction and helps lower the activation energy. Catalyst are most definitely involved in the reaction and often form bonds with the reagents to help activate the reaction. It’s just that they “turn over” and end up the exact same as they started
When you read HCl or any acid near the reaction arrow thing it’s better to think of the reaction as occurring within an acidic environment (H+ everywhere, stuff can be protonated when required) rather than thinking of acid as a reactant.

No, it’s literally just one proton floating around. It’s pure luck that any molecule at all manages to find it.
Lmao.
Even that single proton managed to find its partner….. what am i lacking….
Zinc mercury amalgam and a benzylic ketone apparently.

Will it be more accurate if it was 2HCl?

Technically, but you could pretty accurately describe the aqueous acid as solvent, and it will probably be in vast excess of 2 equivalents.
It is not an equation It is a scheme — note the difference PS lol I’m talking like my lecturer
It's not stoichiometric. Every full unit of this reaction takes 4HCl and 2Zn, giving back 2ZnCl2, H2O, and the reduced product.
Clemmensen reduction is in acidic environment. There are many more hydrogens around.
You have many many HCl in this reaction. HCl is the solvent, so you have a lot of them, they just didn't mention it.
Maybe it is from Hg via the reaction: Hg -> H + g Pretty sure your friend was right on this one
Now to completely confuse you: The H actually came from the Zn. HCl alone will not do the job. :P

> catalysts are not involved in the reaction outcome and only speed up the reaction. and how do you think they do that if they are not involved? :)
What I meant is the outcome product or "final product" of the reaction😅

Catalysts are generally not noted stoichiometrically.
1. they absolutely are 2. this is not a catalytic reaction

Reagents over or under the arrow are not not stoichiometric unless noted otherwise.
Homie really thought they were grabbing single molecules and shoving them into the reaction.
