The strongest intermolecular forces in each case are: CHF3: dipole - dipole interaction OF2: London dispersion forces HF: hydrogen bonding CF4: London dispersion forces Explanation: Each of these molecules is made up of polar covalent bonds; however in order for the molecule itself to be polar, the polarities must not cancel one another out. Few things to consider, in order: Do they contain hydrogen bonds? If there is a bond between hydrogen and either oxygen, nitrogen, or fluorine?

around the world. (a) Reactions are faster at a higher temperature because activation For example, the average bond-energy for \(\ce{O-H}\) bonds in water is 463 kJ/mol. The hydrogen bonds cause this enormous difference in melting point. Intramolecular forces are involved in two segments of a single molecule.

Assuming ideal behavior, which of. A hydrogen atom between two small, electronegative atoms (such as \(\ce{F}\), \(\ce{O}\), \(\ce{N}\)) causes a strong intermolecular interaction known as the hydrogen bond. The energy required to break molecules apart is much smaller than a typical bond-energy, but intermolecular forces play important roles in determining the properties of a substance. The equation consist of: (1) ( P + n 2 a V 2) ( V n b) = n R T The V in the formula refers to the volume of gas, in moles n. The intermolecular forces of attraction is incorporated into the equation with the n 2 a V 2 term where a is a WebSee Answer.
