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.

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
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.
Does carboxylic acid become basic if you place it in water?
Carboxylic acids do not become basic when placed in water. They are weak acids that can donate a proton to water molecules, increasing the concentration of H3O+ ions in the solution. This results in an acidic solution, not a basic one.
Is carboxylic acids inorganic?
No, all the carboxylic acids are organic because they contain carbon and hydrogen and have the living origin.
What is the pka of ch3ch2sh?
The pKa of ethanethiol (CH3CH2SH) is approximately 10.5. This indicates that it is a weak acid, and the thiol group (-SH) can donate a proton in solution. Consequently, it is more acidic than alcohols but less acidic than carboxylic acids.
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.
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.
On the basis of resonance Why carboxylic acids show acidic property?
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.
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
Do carboxylic acids get oxisidized?
Yes, to peroxy carboxylic 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.
Why COOH is an base?
Actually, COOH is not a base; it is an acidic functional group known as a carboxylic acid. Carboxylic acids typically release a proton (H+) in a reaction, making them acidic. Bases, on the other hand, are substances that can accept protons.
Is Carboxylic acid does this contain fat?
No, carboxylic acids are simply a class of organic acids. Some carboxylic acids are fatty acids but are not fats nor do they contain them. Amino acids, the building blocks of protein are also carboxylic acids. One of the most common carboxylic acids is acetic acid, commonly sold as vinegar.
What is the difference between a carboxylate and a carboxylic acid in terms of their chemical properties and reactivity towards other compounds?
A carboxylate is the ionized form of a carboxylic acid, meaning it has lost a hydrogen ion. Carboxylates are generally more stable and less reactive than carboxylic acids. Carboxylic acids are more acidic and tend to react with other compounds to form salts or esters.
Can LiAlH4 reduce carboxylic acids?
Yes, LiAlH4 can reduce carboxylic acids to alcohols.
