Hypofluorous acid (HOF) is the simplest possible compound that allows comparison between fluorine and oxygen in their abilities to form hydrogen bonds. Although F attracts electrons more strongly than O, solid HOFunexpectedly contains no H ... F hydrogen bonds! Draw a proposed structure for chains of HOF molecules in the crystalline state. The bond angle in HOF is 101 degrees.

Complete the following table: Substance F2b.p. –188 °C HFb.p. +20 °C CaF2m.p. +1418 °C SF4 b.p. –40 °C Substance composition (ionic,...)         Physical state at +0 °C         Physical state at –50 °C         Compare physical states at the same T to rank their intermolecular forces (IeFs) in strength: has the strongest IeFs– ____ > ____ > ____ > ____ –has the weakest IeFs

b) Draw a diagram below to showing the strongest intermolecular forces present between molecules of penguinol.» OH Penguinol

1.) A larger dipole will create a stronger intermolecular interaction 2.) If the dipole is sufficiently large, dispersion forces can be neglected 3.) Polar molecules that form dipole-dipole bonds will always have stronger intermolecular networks than non-polar compounds that form dispersion forces only. Which statement or statements, if any, are true?
