Why benzoic acid has a higher melting point than stearic acid?

Why benzoic acid has a higher melting point than stearic acid?

Thanks, is my following answer correct than = First of all, the resonance structure of benzoic acid makes it more stable and gives it stronger intermolecular bindings, whereas stearic acid does not have any benzene ring with the resonance, and therefore benzoic acid has a higher melting point?

Why is the melting point of benzoic acid more than that of formic acid?

However, in case of benzoic acid the benzoic ring is attached directly to the carbonyl group. Thus there is additional resonances between the carbonyl group and the benzene ring which we distubs the carboxylate. Hence, formic acid furnishers H + ions more easily than benzoic acid.

Why do carboxylic acids have high melting points?

Carboxylic acids, similar to alcohols, can form hydrogen bonds with each other as well as van der Waals dispersion forces and dipole-dipole interactions. The presence of dimers increases the strength of the van der Waals dispersion forces, resulting in the high boiling points of carboxylic acids.

What is melting point for benzoic acid?

252.1°F (122.3°C)
Benzoic acid/Melting point

Why would a melting point be higher?

The stronger the intermolecular forces are, the more energy is required, so the higher the melting point is. Many intermolecular forces depend on how strongly atoms in the molecule attract electrons — or their electronegativity.

Does benzoic acid have a high melting point?

Why benzoic acid is more acidic?

The carboxyl group of benzoic acid is attached to an sp2-hybridized carbon which is more electronegative and electron-withdrawing than the sp3-hybridized carbon attached to acetic acid. This stabilizes the negative charge of the conjugate base, increasing the acidity of the carboxylic acid.

Why is benzoic acid stronger than acetic acid but weaker than formic acid?

An electron releasing group i. e+I effect is present in acetic acid whereas no such releasing group is present in formic acid and as we have seen +I effect decreases acidic strenght of an acid . Therefore C6H5COOH(benzoic acid) is stronger than acetic acid(CH3COOH) .

Do acids have a high melting point?

This causes the acids to interact stronger with each other. More importantly, organic acids form dimers (usually) with their hydrogen bonds (acetic acid dimer, for example). For this reason, the packing of the acids in the solid phase is significantly better than that of alcohol; hence the higher melting point.

Why do carboxylic acids have low melting point?

Physical Properties of Carboxylic Acids This reflects differences in intermolecular attractive forces in the crystalline state. In the table of fatty acids we see that the presence of a cis-double bond significantly lowers the melting point of a compound.

Does benzoic acid have high melting point?

How is benzilic acid more acidic than acetic acid?

Although benzoic acid is more acidic than acetic acid. Because, in case of acetic, the carboxylic acid group (-COOH ) is directly attached to the methyl group ( -CH3 ) which have +I effect.

What is the density of benzoic acid?

Benzoic acid, C 6H 5COOH, melts at 122 oC. The density in the liquid state at 130 oC is 1.08 g/cm 3. The density of solid benzoic acid at 15 oC is 1.266 g/cm 3.

What is the odor of benzoic acid?

Description and Tests.—”Benzoic acid occurs in commerce in white, or yellowish-white, lustrous scales or friable needles, odorless, or having a slight, characteristic odor resembling that of benzoin, and of a warm, acid taste; somewhat volatile at a moderately warm temperature, and rendered darker by exposure to light.
