Which of the following statements about London dispersion forces is/are true? Group of answer choices London dispersion forces are stronger between molecules of 1-butanol than between molecules of 2-methyl-2-propanol. London dispersion forces are stronger than hydrogen bonding interactions. both a and b neither a nor b How many different alkene products (counting cis and trans isomers of a compound as a single product) could be produced when 3-methyl-3-pentanol is dehydrated? Group of answer choices 1 2 3 4
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...
The boiling point of iodine (12) is much higher than the boiling point of helium (He). Why? O 12 has a larger electron cloud than He, so more energy is required to overcome the stronger London Dispersion Forces. O It requires more energy to break the covalent bonds in 12 than to overcome the London Dispersion Forces between He atoms. The bonds between iodine atoms are stronger than the bonds between helium atoms and therefore harder to break. O 12...
My answers: Not sure if they are correct. 1. a. London dispersion b. H-bonding, dipole-dipole, london dispersion c. London dispersion d. Ionic, london disperson 2. The second one because not a lot of H+ and less acidic. Need help understanding the meaning of the question. 3. Diethyl cannot h-bond because it does not provide intermolecular bonding engery while 1-b. can form h-bond making strong intermolecular bonds to take up greater engery to break molecules. 4. Not sure...
Which of the following best describes London dispersion forces. Question 1 options: the intermolecular forces that exist when ions from an ionic compound are attracted to the dipole of polar molecules in a mixture. involves molecular orientations in which the positive end of one dipole is near the negative end of another forces that exist only between molecules that contain hydrogen atoms bonded to highly electronegative atoms such as O, N, F. Interactions between temporary dipoles cause atoms to be...
Question 10 (1 point) Which intermolecular force increases with increasing molar mass? OX-forces O dispersion forces O dipole-dipole forces hydrogen bonding O none of the above
Question 6 (1 point) True or False (based on question 20): The eclipse due to an earth sized planet passing in front of a sun sized star takes an amount of time that is of a simmilar size to the orbital period. True False Question 7 (1 point) True or False: As the orbital inclination of the observer (Earth) approaches 90 degrees the amplitude of the radial velocity function approaches a minimum. True False We were unable to transcribe this...
