What is the predominant intermolecular force in HCN? vegan) just to try it, does this inconvenience the caterers and staff? C) (NH4)2CO3 A) strong enough to keep the molecules confined to vibrating about their fixed lattice points Consider that the pressure above the liquid is pressing down on the surface, making it difficult for the molecules to escape into the gas phase. A) a supersaturated solution 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. Except in some rather unusual cases, the hydrogen atom has to be attached directly to the very electronegative element for hydrogen bonding to occur. C. methanol D) Intermolecular forces hold the atoms in molecules together. D. 2-ethoxy-3-ethylcyclohexane (e) Ar < Cl2 < CH4 < CH3COOH. kinetic energy (velocities) to escape as gases at lower temperatures. points is that longer chain molecules become wrapped around and Upper Saddle River, New Jersey: Pearson/Prentice Hall, 2008. 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. Hydrogen sulfide has the highest. C) 1/2 Any molecule which has a hydrogen atom attached directly to an oxygen or a nitrogen is capable of hydrogen bonding. Therefore, molecules with strong intermolecular forces will have higher boiling points.
