This isn't a question, it's a statement. If you are asking why it is because it only donates the hydrogen attached to the oxygen.

Ch3COOH -----> CH3COO- + H+
the hydrogen atom alone can react in a reaction. the other 3 do not. hence, since acetic acid has 1 H atom that can react, it is a monobasic acid

In CH3COOH, only the H that is attached to the carboxylic group can be ionised. Therefore this acid can donate only one proton. Thus it is a monobasic acid.
Basicity of an acid is the number of ionisable H atoms, and not the total number of H atoms in it.

Because only "OH" portion of formula is considered as basic not other atoms.
Like all the Organic avid formula have many Hydrogen atoms e.g.
CH4C2H4COOH but this also is monobasic.

The reason is because only the COOH part makes it acidic and when it dissociates, it dissociates into CH3COO- and H+ and not 4H+, therefore it is monobasic. If you compare this with Sulphuric acid, the dissociation for this is (2H+) + (SO4)2- therefore H2SO4 is dibasic. Hope this helps.

formula a little developped
H3-C-COOH
The 3 Hydrogens of group CH3 are not exchangeable and linked with high energy to the carbon. But in the group COOH , the Hydrogen is linkked to an oxygen which is linked to the carbon. Oxygen can be depleted of the Hydrogen and this hydrogen can be realesed in solution

In organic chemistry, the COOH group is seen as acidic and as acetic acid (CH3COOH) only has one such group, then it is considered monobasic acid.

It is so becuse the electronegativity difference between oxygen and hyadrogen is much more than that between carbon and hydrogen. so the H of CH3 is not replaced and H of COOH is replaced. moreover CH3coo- is a strong base.... for more details ask me by mailing me at udareme_13@yahoo.co.in

That is because in aqueous solutions,only one hydrogen atom out of all the 4 dissociates,forming a hydronium ion.The reaction is:
CH3COOH+H2O<--->CH3COO-+H30+

coz only among 4 only one is acidic (the one that is attached to O atom)
