My Teacher told me that if we react any group 1 metals with Ethanoic acid, then it's "OH" will be replaced by metal. E.g

Na + 2CH3CO2H------> CH3CO2Na + H2

But he said that if we react any metals from group 2 then reaction will happen like this...


1, Mg(s) + 2CH3CO2H(aq) ----> Mg(CH3CO2)2(aq) + H2(g)

however, i asked him whether this was right:

2,Mg(s) + 2CH3CO2H(aq) ----> (CH3CO2)2Mg(aq) + H2(g)
He said that this is absolutely wrong! But in my 2 Chemistry course books also from Chemistry websites i saw this, the above reaction is shown. So my question is: which one is correct way to write this reaction, 1 or 2?

Do you really think you will get different answer here?

u again!! lol   

dude i am just getting different opinion and answers from different people!! 


but u showed up!! what a surprise !!

Sodium ethanoate is sometimes written as CH₃COO^-Na⁺ or simply CH₃COONa, because the negative charge is spread over the carboxylate system. Same thing applicable to Mg.
