• Molecule Polarity Worksheet Answers

  You should try to answer the questions without accessing the Internet. Most substances can exist in either gas, liquid, or solid phase under appropriate conditions of temperature and pressure. The phase that we see under ordinary conditions room temperature and normal atmospheric pressure is a result of the forces of attraction between molecules or ions comprising the substance. The strength of these attractions also determines what changes in temperature and pressure are needed to effect a phase transition. Intermolecular Forces The tendency of a substance to be found in one state or the other under certain conditions is largely a result of the forces of attraction that exist between the particles comprising it. We will concentrate on the forces between molecules in molecular substances, which are called intermolecular forces. Forces that exist within molecules, such as chemical bonds, are called intramolecular forces.

• Lewis Dot, VSEPR Shape, Polarity And Intermolecular Forces Activity Sheet

  The greater the strength of the intermolecular forces, the more likely the substance is to be found in a condensed state; i. As we have seen, the model of an ideal gas assumes that the gas particles molecules or atoms have virtually no forces of attraction between them, are widely separated, and are constantly moving with high velocity and kinetic energy. In truth, there are forces of attraction between the particles, but in a gas the kinetic energy is so high that these cannot effectively bring the particles together. With stronger intermolecular forces or lower kinetic energy, those forces may draw molecules closer together, resulting in a condensed phase. The forces that hold molecules together in the liquid and solid states are called intermolecular forces and are appreciably weaker.

• Lewis Structures Of Atoms Worksheet

  The polarities of individual molecules tend to align by opposites, drawing the molecules together and thereby favoring a condensed phase. These additional forces of attraction must be overcome in a transition to a less-ordered phase e. The interaction between two molecules can be decomposed into different combinations of moment-moment interactions. Often, but not always, these interactions can be ranked in terms of strengths with of interactions involving lower number of moments dominating those with higher moments. However, the relevant moments that is important for the IMF of a specific molecule depend uniquely on that molecules properties. For example, an uncharged molecule will not have a monopole moment and hence will not have monopole-monopole IMF, nor monopole-dipole or monopole-quadrupole IMFs. Similarly, if a molecule does not have a dipole moment nor monopole moment, then quadrupolar interactions will be important.

  The hydrogen bonding IMF is a special moment-moment interaction between polar groups when a hydrogen H atom covalently bound to a highly electronegative atom such as nitrogen N , oxygen O , or fluorine F experiences the electrostatic field of another highly electronegative atom nearby. Then the same interactions discussed above can occur. Examples include permanent monopole charge - induced dipole interaction, permanent dipole - induced dipole interaction, permanent quadrupole-induced dipole interaction etc.

  The first two interactions are the most relevant for our discussion. The strength of the electric field causes the distortion in the molecule. Instantaneous - Induced Charge Distribution IMFs The instantaneous unequal sharing of electrons causes rapid polarization and counter-polarization of the electron cloud in atoms and molecules which generate very short lived dipole moments. The London IMF also called dispersion force is a transient attractive force that results when an Instantaneous dipole on one species then induced a dipole moment on the other. London dispersion forces and dipole-dipole forces are collectively known as van der Waals forces. Molecules can have any mix of these three kinds of intermolecular forces, but all substances at least have London dispersion forces. London dispersion forces exist for all substances, whether composed of polar or nonpolar molecules.

• Phet Activity Molecule Polarity

  They arise from the formation of temporary, instantaneous polarities across a molecule from circulations of electrons. An instantaneous polarity in one molecule may induce an opposing polarity in an adjacent molecule, resulting in a series of attractive forces among neighboring molecules. London dispersion forces arise from changing electron distributions. Because all molecules have electrons, all molecular substances have London dispersion forces, regardless of whether they are polar or non-polar. Molecules with higher molecular weights have more electrons, which are generally more loosely held. This makes their electron clouds more deformable from nearby charges, a characteristic called polarizability. As a result, substances with higher molecular weights have higher London dispersion forces and consequently tend to have higher melting points, boiling points, and enthalpies of vaporization.

The interactions between cations and anions are ionic and are often called ionic bonds. Learners need to be able to identify whether a molecule is polar or non-polar. This means that they firstly need to be able to predict the polarity of the bonds but they also need to be able to work out the shape of the molecule in order to determine if the molecule is polar or not.

Tutorial IsaacsTeach : Intermolecular forces How do particles attract and repel each other? Coulombs law By the end of this unit students should be able to describe the attractive and repulsive forces based on Coulombs law. The law was first published in by French physicist Charles Augustin de Coulomb and was essential to the development of the theory of electromagnetism. The law esentially says that like charges repel and opposite charges attract. The larger the two charges are, the greater the attraction between them. The magnitude of the attractive force is also affected by distance as well. As the distance between particles decreases, the force between the particles increases by the square of the distance.

Hydrogen bonding By the end of this unit students should be able to describe a hydrogen bond and identify it as a type of a dipole-dipole interaction.

  This is because there is a large electronegativity difference between hydrogen and fluorine, oxygen, and nitrogen. As a result of the high electronegativities of fluorine, oxygen, and nitrogen, these elements will pull the electrons almost completely away from the hydrogen. The hydrogen becomes a bare proton sticking out from the molecule, and it will be strongly attracted to the negative side of any other polar molecules. Hydrogen bonding is an extreme type of dipole-dipole bonding. These forces are weaker than intramolecular bonds, but are much stronger than other intermolecular forces, causing these compounds to have high boiling points.
