why are carboxylic acids more acidic than alcohols and phenols?
1342
On the other hand in case of phenols, negative charge is less effectively delocalized over one oxygen atom and less electronegative carbon atoms in phenoxide ion. Therefore, the carboxylate ion exhibits higher stability in comparison to phenoxide ion. Hence, the carboxylic acids are more acidic than phenols.

The acidity of phenols is due to its ability to lose hydrogen ion to form phenoxide ions. ... Thus, the phenoxide ion is formed. The phenoxide ion formed is stabilized by the delocalization of negative charge due to the resonance in the benzene ring.

Carboxylic acids are characterized as weak acids, meaning that they do not fully dissociate to produce H+cations in a neutral aqueous solution.

Phenol is more acidic than cyclohexanol and acyclic alcohols because the phenoxide ion is more stable than the alkoxide ion. In an alkoxide ion, such as the one derived from cyclohexanol, the negative charge is localized at the oxygen atom. ... Phenols substituted with electron-donating groups are less acidic than phenol.

Physical properties : Other lower carboxylic acids are also sour in taste. (iii) Ethanoic acid has boiling point 391 K. Carboxylic acids have higher boiling points than corresponding alcohols, aldehydes and ketones. (iv) Acetic acid is soluble in water, i.e., it is miscible with water in all proportions.

Aldehydes and ketones contain the carbonyl functional group. ... A carboxylic acid contains the carboxyl functional group. They are weak acids because the hydrogen of the hydroxyl group is ionizable. In an ester, the hydrogen of a carboxylic acid group is replaced by an alkyl group.

Phenol is far more acidic than methanol. This is because the phenolate conjugate base is resonance stabilised. The methoxide conjugate base has no such stabilisation, and therefore is formed much more reluctantly.

Structure and bonding The C–H bond is not ordinarily acidic. Because of resonance stabilization of the conjugate base, an α-hydrogen in an aldehyde (not shown in the picture above) is far more acidic, with a pKa near 17, compared to the acidity of a typical alkane (pKa about 50).

The pKa's of benzoic acid and 2-naphthol are 4.17 and 9.5, respectively, while naphthalene is a neutral compound. Since benzoic acid is much more acidic than 2-naphthol, the weak base, sodium bicarbonate, will be able to effectively remove benzoic acid's acidic hydrogen.

The closer the negative ion is to the H+ ion in the molecule, the stronger the acid is. ... The more lopsided it is throughout the molecule, the stronger the acid. A molecule with a triple bond is more acidic than one that only has single bonds.

It is acidic. This is because carbon dioxide dissolved to make aerated drinks combine with water to form carbonic acid.

Vinegar is mildly acidic with a pH of 2–3. Apple cider vinegar is slightly more alkaline than pure vinegar because it contains more alkaline nutrients. However, it's still acidic.

The main difference between mineral acid and organic acid is that mineral acids are inorganic compounds composed of different chemical element combinations whereas organic acids are organic compounds essentially composed of carbon and hydrogen atoms. ... They are highly water-soluble but insoluble in organic solvents.

Organic acids must have functional group - COOH except C6H5OH (Carbolic acid). Although there is carbon in HCN, it is not organic acid because there is no -COOH group.

Esters can form hydrogen bonds through their oxygen atoms to the hydrogen atoms of water molecules. As a result, esters are slightly soluble in water. However, because esters do not have a hydrogen atom to form a hydrogen bond to an oxygen atom of water, they are less soluble than carboxylic acids.

As the number of carbon atoms increases, the solubility of the compound in water decreases. ... Evidence supporting this hypothesis can be found in the fact that diols (compounds with 2 —O–H groups) are more soluble than similar alcohols.

Apple cider vinegar is acidic (low pH) and is high in acetic acid. Dull, brittle, or frizzy hair tends to be more alkaline or higher on the pH scale, and high alkalinity can contribute to friction, breakage, and dryness.
