The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The correct answer is c) London dispersion forces<\/strong>.<\/p>\n\n\n\n

Here is a detailed explanation:<\/p>\n\n\n\n

To determine the type of intermolecular force between two borane (BH\u2083) molecules, we must first analyze the properties of the BH\u2083 molecule itself, specifically its polarity.<\/p>\n\n\n\n

    \n
  1. Bond Polarity:<\/strong>\u00a0The polarity of a chemical bond depends on the difference in electronegativity between the two atoms. The electronegativity of Boron (B) is approximately 2.04, and for Hydrogen (H), it is about 2.20. The difference is very small (0.16), which means the B-H bond is considered nonpolar.<\/li>\n\n\n\n
  2. Molecular Geometry and Polarity:<\/strong>\u00a0According to VSEPR theory, the BH\u2083 molecule has a central boron atom bonded to three hydrogen atoms with no lone pairs on the central atom. This results in a trigonal planar geometry, with the hydrogen atoms arranged symmetrically around the boron atom at 120-degree angles. Even if the bonds had a slight polarity, this symmetrical arrangement would cause the individual bond dipoles to cancel each other out, making the overall molecule nonpolar.<\/li>\n\n\n\n
  3. Evaluating the Intermolecular Forces:<\/strong>\u00a0Now we can evaluate the given options based on the fact that BH\u2083 is a nonpolar molecule.\n
      \n
    • Ion-dipole forces<\/strong>\u00a0occur between an ion and a polar molecule. Since BH\u2083 is a neutral molecule, not an ion, this force is not possible.<\/li>\n\n\n\n
    • Dipole-dipole forces<\/strong>\u00a0are attractive forces that exist between polar molecules. Because BH\u2083 is nonpolar, it does not have a permanent dipole moment, so it cannot experience dipole-dipole forces.<\/li>\n\n\n\n
    • Hydrogen bonding<\/strong>\u00a0is a special, strong type of dipole-dipole force that occurs when a hydrogen atom is covalently bonded to a highly electronegative atom (nitrogen, oxygen, or fluorine). In BH\u2083, hydrogen is bonded to boron, which is not highly electronegative. Therefore, hydrogen bonding cannot occur.<\/li>\n\n\n\n
    • London dispersion forces (LDFs)<\/strong>\u00a0are the weakest type of intermolecular force. They are caused by temporary, instantaneous dipoles that arise from the random movement of electrons within a molecule. These temporary dipoles can induce similar dipoles in neighboring molecules, creating a weak attraction. London dispersion forces are present in all atoms and molecules, but they are the\u00a0only<\/em>\u00a0intermolecular force that exists between nonpolar molecules.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n

      Since BH\u2083 is a nonpolar molecule, the only intermolecular force of attraction between two BH\u2083 molecules is the London dispersion force. The dotted line in the diagram represents this weak, temporary attraction.<\/p>\n\n\n\n
