Which is a stronger acid phenol or acetic acid?

Answer: Acetic acid is more acidic than Phenol. Acetic acid is a typical carboxylic acid and removal of proton from O-H bond is facilitated by electron withdrawing carbonyl group. But Phenol is stabilised by phenoxide ion via resonance and no such property as acetic acid is not observed yet.

Which is a stronger acid water or acetic acid?

The fact that HCl is a stronger acid than the H3O+ ion implies that the Cl- ion is a weaker base than water. The values of Ka for these acids suggest that acetic acid is a much weaker acid than the H3O+ ion, which explains why acetic acid is a weak acid in water.

Which is stronger acetic acid or ethanol?

Because acetate ion has resonance that delocalizes the electron pair to be shared with a proton and ethoxide ion does not, acetate ion is a weaker base than ethoxide ion. Recalling that weaker bases have stronger conjugate acids, we conclude that acetic acid is a stronger acid than ethanol.

Why is phenol A stronger acid than ethanol?

Phenol is more acidic than that of ethanol because phenoxide ion is stabilized through delocalisation. When phenol loses an H+ ion, the ion formed is known as phenoxide ion. Its chemical formula is C6H5−O−. The negative charge formed as a result of losing an H+ ion is not localised in phenol.

Why 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 does ethanol have a higher PH than acetic acid?

Resonance always stabilizes a molecule or ion, even if charge is not involved. The stability of an anion determines the strength of its parent acid. A carboxylic acid is, therefore, a much stronger acid than the corresponding alcohol, because, when it loses its proton, a more stable ion results.

Which is the strongest acid in phenol?

Phenol is a stronger acid than cresol. This is because in cresol CH3 is an electron-donating group which increases the electron density on the oxygen. This means that there is an increase in the electron density in OH bond making cresol weaker acid than phenol.

What is the reason why acetic acid is stronger acid than ethanol?

q Acetic acid is more acidic than ethanol, because the anion of acetic acid, i.e. the acetate anion, is resonance stabilized , but the anion of ethanol is not. In both anions, the negative charge is on oxygen, so the resonance effect is essentially the only differentiating effect.

Which of the following is the strongest acid ethanol phenol and ethanol and benzoic acid?

The correct order of increasing acidic strength is Ethanol < Phenol < Acetic acid < Chloroacetic acid. Phenol is more acidic than ethanol because in phenol, the phenoxide ion obtained on deprotonation is stabilized by resonance.

Is phenol A stronger acid than water?

A hydrogen ion can break away from the -OH group and transfer to a base. For example, in solution in water: Phenol is a very weak acid and the position of equilibrium lies well to the left. Phenol can lose a hydrogen ion because the phenoxide ion formed is stabilised to some extent.

Why is phenol acidic than water?

In this way, negative charge on oxygen is delocalized on to the ortho and para carbon atoms and phenoxide ion becomes a stable resonating structure. This stabilizes the phenoxide ion and makes phenol more acidic than alcohols. Note: Note that phenol is more acidic than water whereas water is more acidic than alcohols.

Why is acetic acid more acidic than phenol?

thats why acetic acid is more acidic than phenol. In ethanol there is no resonating structure after removal of hydrogen ion and it has the +I effect also due of alkyl group which decrease the acidic character.

Why is phenol stronger than other alcohols?

Phenol is a lot stronger than these alcohols because the charge on the anion can be spread throughout the benzene ring. A more direct comparison is benzoic acid C6H5COOH Ka = 6.4 x 10^(–5) with ethanoic acid Ka = 1.7 x 10^(-5).

What is the difference between ethan-1-oic acid and phenol?

Ethan-1-oic acid (M.F. – CH3COOH ) is commonly called Acetic acid and is a Carboxylic acid whereas Phenol is carbolic acid with hydroxyl group present on Benzene ring (M.F.-C6H5OH). Phenol. Ethan-1-oic acid ( Acetic acid )

How do you determine the strength of an acid?

The strength of an acid is usually determined by the relative ease with which it releases its hydrogen as proton (H+ ion) in water. Acetic acid (CH3COOH), phenol (C6H5OH) and ethanol (C2H5OH), all the three have the polar hydroxyl group (O-H) in their molecules. But acetic acid is a carboxylic acid having the CO-OH group, unlike the other two.
