7). a). Is the acetone molecule non-polar or polar? Circle. Non-polar Polar b). Sketch pictures of the intermolecular forces that would occur between the molecules of acetone and the molecules of 2- propanone if you have a mixture of the two liquids. What would be the main type of IMF that is responsible for the attraction? (Give a name for the IMF). c). The pentane molecule and the 2-pentanone molecule both have five carbon atoms on their structures. Why 2-pentanone...
1/Predict the solubility (S for soluble, NS for nonsoluble) of each of the following substances in the solvents water and benzene. (Hint: Like dissolves like) Substance Water (Polar) Benzene (NonPolar) CaCO3 (nonpolar liquid) K2SO4 (polar liquid) NaNO3 (polar liquid) Acetone (polar liquid) Butane (nonpolar liquid) Petroleum (nonpolar liquid) show me the work
2. Why do ionic substances with higher lattice energies tend to be less soluble in water than substances with lower lattice energies? 3. Which would you expect to have the larger hydration energy, SO or CIOA? Explain. 4. Ethyl alcohol, CH CH2OH, is miscible with water at 20°C, but pentyl alcohol, CH3CH2CH2CH2CH2OH, is soluble in water only to the extent of 2.7 g/100 ml. Explain.
Why are many ionic compounds not soluble in water? A. They are non-polar and do not mix well with H2O B. They have metals that are much denser than water C. They have high charge density which makes stronger ionic bonds that water can’t break D. They have weak ionic bonds that cause them to precipitate E. The higher pressure of water causes solids to precipitate
Phospholipids have very long, nonpolar chains with a small polar head. Hence they are soluble in water. True or False
