Indicate whether each of the indicated is more soluble in water (polar solvent) or in benzene (nonpolar solvent) Question 4 options: C6H12 (nonpolar) NaBr (polar) KI (polar) I 2(nonpolar) 1. Water (polar) 2. Benzene (nonpolar)
How is the solvent in D more polar than A? D. Time for 10% Solvolysis of 2-chloro-2-methylpropane in a Different Solvent System Pipet 2.00 mL of the 0.1 M 2-chloro-2-methylpropane solution into a 50-mL Erlenmeyer flask. Place the flask on a sheet of white paper. This will aid you in observing color changes. Into another 50-mL Erlenmeyer, pipet 0.20 mL of the NaOH solution and add 7.80 mL of distilled water. Finally, add a drop of the indicator to the...
the solvent available are water, water mixed with ethanol, ethanol, and toluene. as for the unknown compounds we had: methyl-p-nitrobenzoate acetanilide benzoic acid phenacetin acetylsalicylic acid salicylic acid acetaminophen 4-aminiobenzoic acid Question 4: Look at the 4 solvents that you tested and the possible structure of the unknowns. Is there one solvent that you think might dissolve all these compounds at room temperature? Which one and why does it make sense in terms of IMF. (Hint: "like dissolves like "+...
In a polar aprotic solvent, which nucleophile will be more reactive? H2O or OH- I know that in a protic solvent its OH- but is it the opposite from polar aprotic?
If we change the solvent from non-polar to polar what effect will this have on the frequency of absorption if the ground state is non-polar and the excited state is polar? Will it increase or decrease?
structure for water, showing that it is a polar solvent. for CCle carbon tetrachloride. Is this a polar or non-polar solvent carbon 2 Draw a paw a structure Generally what effect does increasing temperature have on the solubility of a substance? 3. Vhy are "spectator ions" not included in the net ionic reaction? What did you observe in this experiment that tells us whether wax is polar or non-polar? 5. 6. Why does a precipitate form when certain solutions are...
