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 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.
Carboxylic acids are moderately stronger acids than 2-naphthol?
Carboxylic acids are stronger acids due to the more stable conjugate base formed after donation of a proton. The presence of the highly electronegative carbonyl group helps stabilize the negative charge on the conjugate base. In contrast, 2-naphthol is less acidic as the conjugate base formed lacks this stabilizing effect.
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.
Why the melting point of carboxylic acids with even carbon number are greater than odd carbon number carboxylic acids?
Carboxylic acids with even carbon numbers tend to pack more efficiently in the solid state due to the symmetrical arrangement of molecules, leading to stronger intermolecular forces like van der Waals interactions. This results in higher melting points compared to carboxylic acids with odd carbon numbers that have a less compact packing arrangement and weaker intermolecular forces.
Which is more acidic an alcohol or organic acid?
An organic acid is an acid that contains covalent bonds between carbon and hydrogen. All organic acids are weak. An inorganic acid is one that does not meet the above criterion. Most inorganic acids are also weak but a few are strong. Inorganic acids can also be called mineral acids. Acids that contain carbon in their basic structures are known as organic acids. E.g. acetic acid (CH3COOH) Acids that do not contain carbon or carbon compounds are inorganic acids. E.g. hydrochloric acid (HCL)

What Class of organic compound with less than five carbon atoms dissolves in water to form a slightly acidic solution?
These organic substances are called amines.
What is the acid part of an amino acid?
The acid part of an amino acid is the carboxylic acid group, which consists of a carbon atom double bonded to an oxygen atom and single bonded to a hydroxyl group (–COOH). It is responsible for giving the amino acid its acidic properties.
Acdity of pyrrole?
Pyrrole is a weak acid due to the presence of a lone pair on the nitrogen atom that can donate a proton. However, it is generally less acidic than alcohols or carboxylic acids. Its conjugate base, the pyrrole anion, is stabilized by aromaticity.
Are aldehydes acidic?
Owing to the resonance stabilization of the conjugate base, an alpha hydrogen (alpha hydrogen is the hydrogen attached to the carbon adjacent to the carbonyl group) in an aldehyde is more acidic than a hydrogen atom in an alkane, with a typical pKa of about 17.
What is the difference between phenol and carboxylic acid?
The release of the H+ ion or (the proton) is much easier in the carboxylic acid as the Phenoxide ion is more electron dense than the Carboxy ion. this is because of to the lone pairs of electrons on the oxygen atom delocalising into the benzene pi ring activating the ring and making the phenoxide ion more electron dense make in it harder for it to donate a proton. on the coboxy ion the negative charge is Shared between the two oxygen's making it less electron dense. Making it easier for the carboxylic acid to donate a proton making it a stronger acid.
Why are esters compounds also called derivatives of carboxylic acid?
Not all esters are derivatives of carboxilic acid, they could also be derivatives of phosphoric, sulphuric or carbonic (etc.) acids. However, they are called derivatives of 'X' acid because they are formed by reacting an oxoacid ('X') with a hydroxyl compound (alcohol or phenol). See the related link and related question for more information about how esters are synthesized.
