carboxylic acids are more stronger acids this is because in the resonance stabilisation of
carboxylic acid the electron density is more pronounced in two oxygen atoms
also in the reaction of carboxylic acid with an alkali ; for eg; sodium hydroxide
it can donate lone pair of electron to a higher base hence it act as a Lewis acid>.

Why carboxylic acids are less acidic than mineral acids?
Carboxylic acids are less acidic than mineral acids because the carboxylic acid group has resonance stabilization through delocalization of the negative charge over the oxygen atoms, making it less available for donation. In contrast, mineral acids, such as hydrochloric acid, readily donate a proton without this stabilization, resulting in a stronger acidity.
When compared to sulfric acid how strong are carboxylic acids?
Carboxylic acids are weaker acids than sulfuric acid. This is because carboxylic acids have two weak acidic hydrogen atoms compared to sulfuric acid's strong acidic hydrogen atoms. This makes sulfuric acid a stronger acid than carboxylic acids.
Are ketones acidic?
Yes, ketones are weakly acidic compounds. The acidity of ketones is due to the presence of a carbonyl group, which can release a proton to form a resonance-stabilized enolate ion. However, compared to carboxylic acids, ketones are relatively weaker acids.
Why phenols are more acidic than alcohols but less than carboxylic acids?
Phenols are more acidic than alcohols due to the resonance stabilization of the phenoxide ion formed upon deprotonation. This stability lowers the energy of the phenoxide ion, making it easier for phenols to donate a proton. However, carboxylic acids are more acidic than phenols because the carboxylate ion is stabilized by two electronegative oxygen atoms and resonance delocalization, resulting in further stabilization compared to the phenoxide ion.
Is sulfuric acid stronger than carboxylic acid?
Acidity is partly determined by its stability of its conjugate base. Once the acid is deprotonated, it is left with a negative charge. Molecules with double bonded oxygens can participate in resonance, which would spread its negative charge over a larger space. Since sulfonic acid has two double bonded oxygens and carboxylic acids only have one, sulfonic acid is more acidic.

Do carboxylic acid taste sour?
Yes, carboxylic acids typically taste sour. This sour taste is due to their acidic nature resulting from the release of hydrogen ions in solution. However, carboxylic acids are generally unsafe to taste due to their potential toxicity.

What is difference between a carboxylic acid an ester and an amine?
Esters and amides are derivatives of carboxylic acids. Amines are alkylated derivatives of ammonia: carboxylic acid= R-COOH ester= R-COOR amide=R-CONH2 amine= R-NHR
What is the explanation for the acidic strength of carboxylic acids?
Carboxylic acids are organic molecules that include a carboxylic functional group (-COOH). The functional group consists of a carbon center, with a double bonded oxygen and a single bonded hydroxol (OH) group.Acids are characterized by the ability to donate or release protons when dissolved in solution. The easier the protons, or H+ ions, are released into solution the more acidic the molecule.The hydroxol group (OH) releases H+ (hydrogen ion) readily when dissolved in solution, forming the conjugate base ( -COO- ).Typical pH ranges of carboxylic acids, such as ethanoic acid, are from 2-3. Methanoic acid is slightly more acidic, with a pH of about 1.5-2.5.
Do carboxylic acids get oxisidized?
Yes, to peroxy carboxylic acids.
what is the correct order of acidic strength?
The correct order of acidic strength is as follows: strong acids > weak acids > organic acids. Strong acids completely dissociate in water to release H+ ions, making them the most acidic. Weak acids partially dissociate in water, while organic acids generally have a carboxylic acid group and are typically weaker acids.
Is the carboxyl group basic or acidic?
The carboxyl group is acidic because it can donate a proton (H+) to a solution, resulting in the formation of a carboxylate ion. This characteristic makes carboxylic acids weak acids in solution.
What is the pH of diluted carboxylic acid?
The pH of diluted carboxylic acids can vary depending on the specific acid and its concentration. Carboxylic acids typically have pH values in the range of 2 to 5 when diluted in water. The presence of the carboxyl group (COOH) in carboxylic acids causes them to be weak acids, leading to slightly acidic pH values when diluted.
