What is the difference between a carboxylic acid and a peroxy acid?

In a peroxy acid (RCOOOH) the anion (RCOOO-) left after the release of H+ cannot be resonance stabilised. However the anion (RCOO-) is stabilised in case of carboxylic acid (RCOOH) due to resonance.

Why are alcohols weaker acids than carboxylic acids?

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. In contrast, electron-donating groups decrease acidity by destabilizing the carboxylate ion.

What does peroxy acid do?

The peroxy acids are used primarily as oxidizing agents; they readily add oxygen to alkenes to give epoxides and are used to convert ketones to esters and amines to nitro compounds, amine oxides, or nitroso compounds.

Which of the following is not a peroxy acid?

Perchloric acid
Perchloric acid is not a peroxy acid while other given acids are examples of peroxy acids.

Why are carboxylic acids weak acids?

Carboxylic acids are weak acids because they only partially ionise in solution. Their solutions do not contain many hydrogen ions compared to a solution of a strong acid at the same concentration. In a weak acid, few of the molecules are ionised.

Why are alcohols weak acids?

Like water, alcohols are weak acids and bases. This is attributed to the polarization of the O–H bond making the hydrogen partially positive. Moreover, the electron pairs on the oxygen atom of alcohol make it both basic and nucleophilic.

Why are phenols a weak acid?

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. The negative charge on the oxygen atom is delocalised around the ring. That is why phenol is only a very weak acid.

Why is carbonic acid weaker than carboxylic acid?

The conjugate base of carbonic acid is carbonate ion which gets resonance stability by forming three equivalent resonating structure whereas conjugate base of carboxylic acid (carboxylate ion) is less stable because it forms two equivalent resonating structure. Therefore , carbonic acid is more acidic.

Why are carbonic acids weak?

H2CO3 is a weak acid that dissociates into a proton (H+ cation) and a bicarbonate ion (HCO3- anion). This compound only partly dissociates in aqueous solutions. These are the reasons why carbonic acid is classified as a weak acid rather than a strong acid.

Is peroxy acid an organic compound?

Peracetic acid (also known as peroxyacetic acid, or PAA), is an organic compound with the formula CH3CO3H. This organic peroxide is a colorless liquid with a characteristic acrid odor reminiscent of acetic acid. It can be highly corrosive. Peracetic acid is a weaker acid than the parent acetic acid, with a pKa of 8.2.
