Why is acetic acid stronger acid than phenol?

Here in acetic acid if we draw resonating structure then same negative charge resides on oxygen atom but if we draw the resonating structure of phenol the negative charge move on from oxygen to carbon and it becomes a non equivalent structure. Hence acetic acid is more acidic than phenol.

Why is acetic acid stronger than phenol whereas formic acid is stronger than acetic acid?

Acetic acid is carboxylic acid and Carboxylic acids are acidic due to resonance stabilization of carboxylate anion and in phenols, acidic character is present due to resonance stabilization of phenoxide anion. So Formic acid is more acidic than acetic acid.

Why Is carboxylic acid a stronger acid than phenol?

Carboxylic acids dissociate in water to form carboxylate ion and the hydronium ion. The carboxylate ion formed is stabilized through resonance by effective delocalization of the negative charge. Hence, the carboxylic acids are more acidic than phenols.

Why acetic acid is stronger than alcohol?

(a) Acetic acid is a stronger acid than ethyl alcohol because the acetate ion formed by ionisation is stabilized by resonance while the ethoxide ion has no resonance. The negative charge in acetate ion is delocalized over two oxygen atoms while the negative charge in ethoxide ion is localized on the single oxygen atom.

Why is acetic acid a stronger acid than acetone?

We’ll see the stabilization of anion that is formed after the removal of proton. Therefore , delocalisation in first is giving more stability to anion generated , hence acetic acid will easily release proton easily. That is why we call it more acidic than acetone.

Why is formic acid stronger than phenol?

Here, formic is a stronger acid because the delocalization of negative charge after losing proton is more delocalized in formate ions on two oxygen atoms. Whereas, in phenoxide ion, we can see oxygen being more electronegative will always have higher charge density even after ring delocalization.

Why are carboxylic acids stronger than carbonic acid?

It is the same reason why carboxylic acid are tested using sodium bicarbonate. Also, it is weaker than the collective reaction of conversion of carbonic acid to carbonate ion. Hence, carbonic acid is weaker when reaction stops in between and stronger when reaction of losing H+ ion goes to the end.

Which is more stable acetate or acetic acid?

For acetic acid, however, there is a key difference: a resonance contributor can be drawn in which the negative charge is localized on the second oxygen of the group. The acetate ion is that much more stable than the ethoxide ion, all due to the effects of resonance delocalization.

Why the acid strength of alkyl acetic acid decreases with the increasing size of alkyl group?

Summary: the slight difference in acidity between both carboxylic acids is due to the inductive effect of the alkyl group which donates electrons. Dear Jason, as a matter of principle the acidity of a carboxylic acid will decrease with increasing length of alkyl chain.

Is acetic acid a strong acid?

A strong acid is an acid which is completely ionized in an aqueous solution. Hydrogen chloride (HCl) ionizes completely into hydrogen ions and chloride ions in water. A weak acid is an acid that ionizes only slightly in an aqueous solution. Acetic acid (found in vinegar) is a very common weak acid.
