D) dispersion forces, dipole-dipole forces, and hydrogen bonds C) mineral The vapor pressure will be higher (more gas molecules are present) In the case of Q3, there is another force acting of $\ce{HF}$ other than London dispersion and van der Waals forces: H-bonding, which would overcome effects on molecular mass and other forces in this case. and boiling data? In state I the maximum value of the magnetic quantum number is m=3m_{\ell}=3m=3; in state II the corresponding maximum value is m=2m_{\ell}=2m=2. B. A larger molecule is more polarizable, which is an attraction that keeps the molecules together. When observing a pot of water on the stove, you know that the water is boiling when you see bubbles that rise to the surface and pop. 3rd ed. Secondary and tertiary alcohols undergo elimination reactions when heated in the presence What is the common name for (CH3)2CHCH2OCH(CH3)2? D) ion-dipole attraction between water and octane molecules The boiling points of ethanol and methoxymethane show the dramatic effect that the hydrogen bonding has on the stickiness of the ethanol molecules: The hydrogen bonding in the ethanol has lifted its boiling point about 100C. This is a consequence of the increased kinetic energy needed to break the intermolecular bonds so that individual molecules may escape the liquid as gases. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Posted 6 years ago.
