2. Which of the followings are true:
A. Ionic interactions are weak bonds in some conditions (aqueous) |
||
B. Hydrophobic interactions are caused by attraction between two hydrophobic molecules |
||
C. Van de Waals interactions may generate significant interactions if at a large number |
||
D. Weak bonds may allow for repeated interactions between molecules |
* The answer A, B, C, D is incorrect
A. is true
Within an aqueous environment, the interaction between ions of opposite charge is minimum. So ionic bonds become weak.
B. is false
Hydrophobic interactions are mainly due to repulsion interaction.
C. is false
Vanderwaals force is dependent on the distance between interacting molecules, not he number.
D. is true
eg - Hydrogen bond

Question 6 0.2 pts Which statement about intermolecular forces is true? Only occur in ionic bonds. They have to be overcome to decompose a substance. These forces hold atoms together in a molecule. They are responsible for the physical properties of matter. Question 7 0.2 pts What intermolecular force is responsible for the attraction between an ion and a polar molecule? O Dipole-dipole interaction Hydrogen bonding lon-dipole interaction London dispersion forces Question 8 0.2 pts of liquids will be related...
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...
