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.

The standard molar heat of formation of water is –285.8 kJ/mol. (b) Why is the magnitude of this value so much larger than the heat of vaporization of water (ΔH°vap = 41 kJ/mol)? Choose one: A. More energy is needed to break attractive forces between w
i need help with this a little bit. The standard molar heat of formation of water is –285.8 kJ/mol.b) Why is the magnitude of this value so much larger than the heat of vaporization of water (ΔH°vap = 41 kJ/mol)?Choose one:A. More energy is needed to break attractive forces between water molecules than to break H–H and O–O bonds and form H–O bonds.B.

Because water molecules can form a variety of hydrogen bonds
with each other, water molecules tend to have more configurations
when they are by themselves than when they are mixed with other
molecules that cannot form hydrogen bonds. Imagine that the
interactions between water molecules and the molecules of a non
polar substance A (W-A interactions) are stronger than the W-W and
A-A interactions. In this case one can predict that:

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...

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...

D. Addition of sulfuric acid to a flask of water is observed to increase the temperature of the flask. The creation of the mixture can be thought of as breaking interactions between water molecules (i.e., water - water interactions), breaking interactions between sulfuric acid molecules (i.e., sulfuric acid - sulfuric acid interactions) and forming new interactions between water and sulfuric acid (i.e., water - sulfuric acid interactions).
