Question

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 dipole-dipole forces between KCl and water help to separate the KCl units within the crystals (D) Diagram 2. because the hydrogen bonds between water molecules expand to accommodate the KCl particles and pull them into solution

Answer 1

Ans A

First Kcl dissociation occur in K+ & Cl - , after that K + is surrounding by partial -ve of O in H2O and cl- by partial positive of H2O by strong ion dipole interaction.
