Question

sess ion.masteringchemistry.com K HW 6 Give It Some Thought 13.2 2016 Constants | Periodic Table or Part A Why doesn't NaCl dissolve in nonpolar solvents such as hexane, CH14? Na+ and Cl ions are spherically symmetric while Ce H14 molecules are not. Therefore, the ions do not fit into the cavities between Ce Hia molecules. Interactions between ions and nonpolar molecules tend to be very weak. Thus, the energy required to separate the ions in NaCl is not recovered in the form of ion-CHi interactions Na+ and C ions are small relative to CeH14 molecules. Therefore, they do not fit into the cavities between C6H14 molecules. There are no dispersion attractive interactions between ions and CeH14. Thus, the interaction between them is very weak and does nor recover the Tex energy required to separate the ions. Submit uest Answer Cheg erin tio Provide Feedback Next> all s mi

Explanation / Answer

Part A : There are no dispersion attractive interactions between ions and C6H6.Thus the interaction between them is very weak and does non recover the energy required to separate the ions.

Part B: The hydrogen atom in a water molecule points towards a electronegative atom that is attached 2 oxygen which is highly electronegative. This is called hydrogen bond..
