Question 3 Intermolecular (IM) Forces are: stronger than covalent bonds stronger than ionic bonds but weaker than covalent bonds weaker the covalent bonds stronger than covalent bonds but weaker than ionic bonds stronger than ionic bonds No new data to save. Last checked at 10:40am 30
1.Which attractions are stronger: intermolecular or intramolecular? 2.How many times stronger is a covalent bond compared to a dipole-dipole attraction? 3.What evidence is there that nonpolar molecules attract each other? 4.Which chemical in table 10.1 has the weakest intermolecular forces? Which has the strongest? How can you tell? 5.Suggest some ways that the dipoles in London forces are different from the dipoles in dipole-dipole attractions. 6.A) Which would have a lower boiling point: O2or F2? Explain. B) Which would have a lower boiling...
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...
7. If an ionic bond is stronger than a dipole-dipole interaction, how can water dissolve an ionic compound? None of these The ion-dipole interactions of a bunch of water molecules gang up on the strong ionic bond and pull it into the solution. The ions never overcome their interatomic attraction and therefore are not soluble. The ionic bond is weakened by the ion-dipole interactions and ionic repulsion ejects the ions from the crystal. The ion-dipole...
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...
123. Which of the following statements is/are true? I. Because ionic forces are so much stronger than hydrogen bonds, no ionic compound will be soluble in ethanol (CH3CH2OH) II. Making of any solution in which a solid is dissolved in a liquid will always have a positive entropy. III. the heats of hydration of ions increase (become more exothermic) as ionic charge increases a. I and II only b. I and III only c. II and III only d. all...

[ Select ] 2) A covalent bond is formed through the transfer of electrons from one atom to another. True 3) When two atoms form a chemical bond, they lower the potential energy between the bonding atoms or ions. (Select]
