What kind of force existed between the molecules of water and molecules of oil?

Most oils are non-polar, so usually, the primary intermolecular force between their molecules are London dispersion forces, caused by the random motion of electrons forming temporary dipole moments across the length of the molecule.

∙ 12y agoIn water, which is composed of hydrogen and oxygen there is a large difference in electronegativity, meaning that the oxygen has a stronger pull on electrons. This, combined with the bent shape of a water molecule, results in a polar substance, with the oxygen end having a partial negative charge and the hydrogen end having a partial positive charge. As a result, water molecules are attracted to one another in much the same manner as magnets with the positive end of one molecule attracted to the negative end of another.
By contrast oils, which are usually composed of hydrocarbons or lipids, have mostly carbon-hydrogen bonds. There is only a fairly small difference in electronegativity between carbon and hydrogen. This results in a less polar bond. Also, these bonds are in a rather symmetrical arrangement, so what little polarity there is cancels itself out. As a result, oils do not experience the same polar attraction that water does.

Why does water wet glass and mercury does not?
Water wets glass because the force of adhesion between the glass molecules and water molecules is greater than the force of cohesion between the water molecules and glass molecules. Mercury does not wet glass because the force of cohesion is greater than the force of adhesion
Why does a concave meniscus form when water is in a graduated cylinder?
The force between glass and water are stronger than between water molecules
What is the attracting force among water molecules and with the molecules of surrounding materials?
capillary action
In steam are the forces between molecules the same as the forces between the molecules in water?
No, they are not. The forces between molecules in steam are not as strong as those present in liquid water.
What are the weak chemical attraction between water molecules?
Water molecules form hydrogen bonds to other water molecules.
What is the definition of adhesion force?
Adhesion force is the force of attraction between molecules of different kind. Eg.adhesion force exists between the molecules of water and the molecules of its containing vessel.
What is the definition of cohesion force?
Cohesive force is the force of attraction between molecules of the same kind or of the same substance. Eg. cohesive force of attraction exists between water molecules
Which property allows water to stick to glass?
This is called adherence. It is the force of attraction between the water molecules and the glass molecules.
Why water has this additional intermolecular force?
Hydrogen bonds between molecules
Why does water wet glass and mercury does not?
Water wets glass because the force of adhesion between the glass molecules and water molecules is greater than the force of cohesion between the water molecules and glass molecules. Mercury does not wet glass because the force of cohesion is greater than the force of adhesion
What is the attractive force between water molecules known as?
This is an intermolecular attraction of water molecules, associated by hydrogen bonds.
Why does water have a meniscus?
Surface Tension. this is caused by a cohesive force between the polarized water molecules.
Why does a concave meniscus form when water is in a graduated cylinder?
The force between glass and water are stronger than between water molecules
Whats the difference between adhesion and cohesion?
Adhesion is the attraction between two molecules of different substances.cohesion is the attraction between molecules of the same substances.
Why is there a force of attraction between water molecules?
The property of cohesion describes the ability of water molecules to be attracted to other water molecules, which allows water to be a "sticky" liquid. Hydrogen bonds are attractions of electrostatic force caused by the difference in charge between slightly positive hydrogen ions and other, slightly negative ions.
How does cohesion help water and minerals flow?
cohesion helps water and minerals flow because... water molecules cling to each other as a result of a force called cohesion cling to molecules of other substances, too , and this force is calledadhesion. This forces water to climb up tubes of xylem tissue.
What type of bond between the atoms forming water molecules?
Hydrogen bonds are the strongest intermolecular force between water molecules, it occurs between a negatively charged oxgen atom of one water molecule and the positively charged hydrogen atom. This is the strongest inter molecular force there is.
