Does Oleic acid have larger molecules than water molecules? and what type of bonding does oleic bonds have?

Of course it is larger http://kaffee.50webs.com/Science/labs/Chem/Lab-Size.of.Molecule.html

It has many more molecules than H2O

Notice it is a covalent chain, with a Hydrophillic and an hydrophobic end.
Within the molecule, it is all covalent, The hydrophobic end will attract water molecules, and the hydrophillic area will be attracted to other covalent chains.

To determine whether oleic acid has larger molecules than water molecules, we need to compare their molecular structures.

Oleic acid (C18H34O2) is a fatty acid consisting of a long hydrocarbon chain with a carboxylic acid (-COOH) functional group at one end. It is a type of organic compound that is mainly found in vegetable oils and animal fats.

Water (H2O), on the other hand, is a small inorganic molecule composed of two hydrogen atoms bonded to one oxygen atom. It has a simple and compact structure.

In terms of molecular size, oleic acid indeed has significantly larger molecules than water. The hydrocarbon chain in oleic acid contributes to its larger molecular size compared to the simple structure of water.

Regarding the bonding in oleic acid, it primarily consists of covalent bonds. Covalent bonds are formed when two atoms share electrons in order to achieve a stable electron configuration. In oleic acid, the carbon and hydrogen atoms in the hydrocarbon chain are bonded together by covalent bonds. The carboxylic acid group (-COOH) is also bonded through covalent bonds between carbon, oxygen, and hydrogen atoms.

It's worth noting that oleic acid can also form weak intermolecular forces, such as van der Waals forces or London dispersion forces, due to the presence of the nonpolar hydrocarbon chain. These weak forces allow oleic acid molecules to interact with each other, for example, in the formation of a liquid or solid state.
