HHHH RocS) yao HOH HH " HHOH Diagram 1 Diagram 2 Which of the diagrams above best represents the interactions that are responsible for the relatively large solubility of KCI crystals in water and why? ) Diagram 1, because strong ion pole interactions between KCl and water help to dissociate the solute. Diagram 1, because strong London dispersion forces between the K and Clions and water replace the weak London dispersion forces between two water molecules. Diagram 2, because strong...
Question 14 Which of the following is or are true? Molecules which have hydrogen bonded to F, 0, or N can undergo hydrogen-bonding London dispersion forces are the result of permanent dipoles in atoms or molecules. Bonding forces are much stronger than intermolecular forces. An intermolecular force is an attractive force that operates between molecules. London dispersion forces occur in all atoms and molecules.
5. Which of the following molecules form complex structures linked by covalent bonds through Lys, HyLys, or His residues? A) Collagen B) Alpha keratin C) Hemoglobin D) Myoglobin E) Beta barrels 6. Which of the following correlates to the classic experiment demonstrating that reduced and denatured RNase A could refold into the native form? A) Disulfide bonds do not stabilize folded proteins B) Reducing agents denature proteins C) 1° structure can determine 3° structure D) Urea cleaves disulfide bonds E)...
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
What intermolecular attractions will be formed when the following substances condense from the gas phase? X Incorrect. Is this molecule polar or capable of hydrogen bonding? Recall that London forces occur between all molecules. (a) hexane (CH34) hydrogen bonding lonic bonding dipole-dipole London forces x Incorrect. Is the oxygen bound to an H, or is this an ether, which cannot hydrogen bond? Recall that all molecules will have London forces. (b) acetone (HACCOCH) London forces hydrogen bonding dipole-dipole (c) jodine,...
