5.32 (a) Solid methane is held together only by London forces, whereas chloromethane is held in solid form by both London forces and dipole-dipole forces. Acetic acid will exhibit London forces, dipole-dipole interactions, and hydrogen bonding. (b) The melting points should increase in the order: 4 3 3 CH ( 183 C) CH Cl ( 97 C) CH COOH (16 C) - < - < . 5.36 For a picture of the simple, a.k.a. primitive, cubic unit cell, see Figures 5.28 and 5.33a. (a) There are eight atoms at the eight corners of the unit cell. One-eighth of each of these atoms will lie in the unit cell for a total of one atom per unit cell. (b) Each atom will be bonded to six atoms that form an octahedron. (c) The edge length of the unit cell for a primitive cubic cell will be twice the atomic radius of the atom or 334 pm in this case. 5.48 Ti atoms at corners: 1 1 8 8 corners atom corner 1 - = Ti Ca atoms: 1 atom at center = 1 Ca O atoms: 12 atoms, one on each edge gives 1 1 4 12 edges atom edge - or 3 atoms: 3 O empirical formula = CaTiO
