The melting point of stearic acid is higher than that of oleic acid. This is because stearic acid has a straight chain structure with saturated fatty acids, leading to stronger intermolecular forces and a higher melting point compared to oleic acid, which has a bent or kinked structure with unsaturated fatty acids.

Why does stearic acid has a high melting point than oleic?
Stearic acid has a higher melting point than oleic acid because stearic acid is a saturated fatty acid, which means it has straight, uniform chains that pack tightly together, leading to stronger intermolecular forces. In contrast, oleic acid is an unsaturated fatty acid with a kink in its carbon chain due to a double bond, which results in weaker intermolecular forces and a lower melting point.
Why is the melting point of Palmitoleic acid lower than that of oleic acid?
The presence of a cis-double bond at a higher position in oleic acid compared to palmitoleic acid increases the intermolecular forces between oleic acid molecules. These stronger intermolecular forces in oleic acid require more energy to overcome, resulting in a higher melting point compared to palmitoleic acid.
Why is there a difference in melting points of stearic acid and oleic acid?
Acetic acid has a very small nonpolar end consisting of just a methyl group counteracted by a carboxylic acid. The carboxylic acid has the ability to deprotonate and become charged, hydrogen bond, and is quite polar. All of these factors contribute to its ability to interact readily with an aqueous solvent such as water through h-bond interactions. Stearic acid, on the other hand, contains the same carboxylic acid functional group, however this group is far outweighed by the very, very long saturated nonpolar carbon chain. The aqueous solvent has nothing to interact with and therefore the stearic acid would rather interact via Van der Waals interactions with itself.
Which is Enzyme responsible for conversion of stearic acid to oleic acid?
The enzyme which catalyzes the conversion of stearate to oleate is stearoyl-CoA desaturase.
What happens when oleic acid is added to water?
Oleic acid is a fatty acid that is insoluble in water due to its long hydrocarbon chain. When added to water, oleic acid will form a separate layer on top of the water due to its hydrophobic nature. This separation is due to the difference in polarity between the water molecules and the nonpolar oleic acid molecules.

What type of fatty acids are used in soap?
In soap making, a combination of saturated and unsaturated fatty acids are used. Common fatty acids include lauric acid, stearic acid, oleic acid, and linoleic acid. The specific types of fatty acids used can vary depending on the desired properties of the soap.
