30. Identify the most important types of interparticle forces present in the solids of each of the following substances. a. NH_(4)Cl b. Teflon, CF_(3)(CF_(2)CF_(2))_(n)CF_(3) C.Polyethylene, CH_(3)(CH_(2)CH_(2))_(n)CH_(3) d. CHCl_(3) e. NH_(3) f. NO g. BF_(3)

a. : The most important interparticle forces present in the solids of are ionic forces between the ammonium ion ( ) and the chloride ion ( ).b. Teflon, : The most important interparticle forces present in the solids of Teflon are van der Waals forces (London dispersion forces) due to the nonpolar nature of the polymer chains.c. Polyethylene, : The most important interparticle forces present in the solids of polyethylene are van der Waals forces (London dispersion forces) due to the nonpolar nature of the polymer chains.d. : The most important interparticle forces present in the solids of (chloroform) are dipole-dipole forces due to the polar nature of the molecule.e. : The most important interparticle forces present in the solids of (ammonia) are hydrogen bonding forces between the hydrogen atoms and the nitrogen atom.f. NO: The most important interparticle forces present in the solids of NO (nitric oxide) are van der Waals forces (London dispersion forces) due to the nonpolar nature of the molecule.g. : The most important interparticle forces present in the solids of (boron trifluoride) are van der Waals forces (London dispersion forces) due to the nonpolar nature of the molecule.
