C The boiling point of H,O is much higher than the boiling point of HS. H2O is a molecular compound, while HS is an ionic compound. H2O is a polar molecule, so the attractions between the molecules are stronger than those between nonpolar H2S molecules. H2O has strong hydrogen bonds between its molecules, and HS molecules cannot form hydrogen bonds. The dispersion forces between the H2O molecules are much stronger. d The boiling point of CH,O is much higher than...

h of the following statements is NOT true? London dispersion forces are present in all substances but are the only significant intermolecular forces in nonpolar substances. ) The density of the liquid state of a substance is greater than the density of its gaseous state. The thermal energy in a liquid allows the atoms within molecules to completely overcome the attractions between them so they flow. Most liquids can be converted to a gas by reducing pressure and/or heating. The...

2. Identify the strongest type of intermolecular forces in acetone, ethanol, water and hexane. (Structures listed on page 15.) Experiment 2 Intermolecular Forces There are three general types of intermolecular forces. All substances exhibit London Dispersion Forces (LDF), and they are generally the weakest of the three types. These London forces are due to the attractions between small, temporary dipoles that arise from the constant, random movement of the electrons in a substance. As molar mass increases, the size of...

(b) Why is the magnitude of this value so much larger than the heat of vaporization of water (AH°vap = 41 kJ/mol)? * Choose one: A. Less energy is needed to form attractive forces between water molecules than to break H-H and O-O bonds and form H-O bonds. O B. More energy is needed to form attractive forces between water molecules than to break H-Hand O-O bonds and form H-O bonds. o C. Less energy is needed to break attractive...

1. Why is the boiling point of 1-butene higher than the boiling point of 1-propene? Group of answer choices Because 1-butene has a different (and stronger) type of atom-to-atom intermolecular interaction than does 1-propene. Because 1-butene forms H bonds and 1-propene does not. As a larger compound, 1-butene can form more atom/atom intermolecular interactions than can 1-propene. None of the above reasons is correct. 2. An ethene molecule contains 4 H atoms. How many H bonds could ethane participate in...

Why does benzene have a much higher boiling point (80。c) than hexane (69。c), even though they have the same number of carbons? A) Benzene is much more polar than hexane which enhances the attractive forces between molecules and raises the boiling point. B) Benzene has fewer hydrogens than hexane. C) Benzene is planar and has delocalized electron density which increases the attractive forces between molecules and raises the boiling point. D) Benzene can covalently bond to another benzene molecule which...

Part A H,0 (100°C) has a higher boiling point than CH, OH (65°C). There are more hydrogen bonds between water molecules than between alcohol molecules. There are less hydrogen bonds between water molecules than between alcohol molecules. CH, OH has the higher molecular mass than H,O. There are no hydrogen bonds between alcohol molecules while there are plenty of them between water molecules.

bonding engery while 1-b. can form h-bond making strong
intermolecular bonds to take up greater engery to break
molecules.
