Feb 2021 solubility in water? A. Na+ and Clions are favorable sites for H-bonding to form. . The ions in Nacl participate in on-induced dipole attractions with water. * The presence of charged ends in NaCl enables dipole-dipole interaction with U. London dispersion forces in NaCl predominate leading to strong dipole interactions with water. water. 19. Xenon (Xe) has a greater atomic weight than Neon (Ne). Xe has 131.3 amu while Ne has 20.2 amu, The melting points are 166.1K and 27.3K, respectively. How do intermolecular forces account for the difference? A. Dipole- dipole interaction is greater in Xe than Ne so more energy is needed to break the bonds. B. H-bonding is greater for substances with higher atomic weight so greater energy is needed to change Xe to vapor. C. Atomic weight increases the chance of lesser dispersion forces so greater energy is neede D. London dispersion forces is greater in substances with heavier atomic weight so greater energy is needed to separate the atoms of Xe than Ne. to separate Xe atoms to change to vapor. 20. Which of the following is a CORRECT pair? A. Glyceride: Polysaccharide B. Glucose: Trisaccharide C. Starch: Polysaccharide D. Sucrose: Monosaccharide 21 Which of the following statements Is TRUE?
