Which of the following dissolves in water because of ion-dipole attractions?
|
|
Sugar
|
|
|
Ethanol
|
|
|
Sodium chloride
|
|
|
Carbon dioxide
|
Explanation:
Detailed explanation-1: -When sodium chloride dissolves in water, the sodium and chloride ions and the polar water molecules are strongly attracted to one another by ion-dipole interactions. Was this answer helpful?
Detailed explanation-2: -These attractions of the water molecule to the sodium and chloride ions are stronger than the ionic bond that holds the salt together so the bond between the Na and Cl breaks. Thus, the salt dissolves, or disassociates into its respective ions (i.e. sodium Na+ and chlorine Cl-), thereby forming an ionic solution.
