What is the most significant intermolecular force acting between molecules of ch3cl

Dipole-dipole interactions.

There are three classes of intermolecular interactions: London dispersion force, Dipole-dipole interaction, and hydrogen bonds.

Hydrogen bonds are observed only in molecules with hydrogen atoms bonded directly to atoms of fluorine, oxygen, or nitrogen that are of high electronegativity. Chloromethane contains no such bonds. Therefore, there would be no hydrogen bonds between molecules of .

Dipole-dipole interactions are weaker than hydrogen bonds in most molecules. Dipole-dipole interactions exist only between polar molecules. Chloromethane contains polar carbon-chlorine bonds. Chloromethane molecules are asymmetric, such that polarity due to the presence carbon-chlorine bonds does not cancel out within the molecule. Chloromethane molecules are therefore polar, and would experience dipole-dipole interactions.

London distribution forces attribute to the movement of electrons within a molecule. Such interactions are transient and thus weaker than both hydrogen bonds and dipole-dipole interactions in small molecules such as .

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
