CHCl3 is a tetrahedron, with the H-side being somewhat positive and the Cl-plane being somewhat negative. Thus, there are dipole-dipole interaction Answer: HF has the higher boiling point because HF molecules are more polar. Classify intermolecular forces as ionic, covalent, London dispersion, dipole-dipole, or hydrogen bonding. Dipole-dipole and dispersion forces must be overcome to boil. The steric number in the case of CH3Cl is 4. The C-Cl bonds are polar but, because of the tetrahedral symmetry, the bond dipoles cancel each other. The positive charge attracts the electrons in an adjacent molecule. Acetic acid melts at 16 C. 0000002221 00000 n
