Pentane with another molecule of pentane: E A compound can be separated into different elements with their own unique properties. The Hydrogen bonding occurs when the partially negative oxygen end of one of the molecules is attracted to the partially positive hydrogen end of another molecule. You find that the smaller alcohols methanol, ethanol, and propanol dissolve easily in water, at any water/alcohol ratio that you try. So now we can define the two forces: Intramolecular forces are the forces that hold atoms together within a molecule. They are also known as Van der Waals forces, and there are several types to consider. And so that's different from an intramolecular force, which is the force within a molecule.

What experience do you need to become a teacher? Wiki User. With increased branching of the carbon skeleton, the surface area of the alcohol decreases (see Chapter 3) and the molecule becomes more nearly spherical. Answer: For any large molecule, the dispersion forces (a.k.a., "instantaneous dipole-induced dipole") forces dominate over the orientation forces (permanent dipole-permanent dipole) and induction forces (permanent dipole-induced dipole). When intermolecular forces are strong the atoms, molecules or ions are strongly attracted to each other, and draw closer together. This occurs when there is a polar bond between two atoms.
