Which compound (water, acetone, ethanol, hexane, decane, or 1-decanol) do you think will be the least volatile and explain why. You must discuss intermolecular forces in your explanation.
The volatility order for above compounds will be :
water > 1-decanol > ethanol > acetone > decane > hexane
1. Water and alcohol both are polar covalent molecules but still water is least volatile because water forms more strong hydrogen bonds in comparison to alcohols as water has two hydrogen atoms it can form two hydrogen bonds while ethanol can form only one hydrogen bond.
2.Comparing the two alcohols (1-decanol and ethanol) 1-decanol is less volatile than ethanol because as the molecular weight increases boiling point increases. remember, alcohols not only have hydrogen bonding but they also have van der waals dispersion forces.so as the chain length increases van der waals forces increases and boiling point increases.
3.Acetone is less volatile than non polar compounds (hydrocarbons).this is because acetone has polar carbonyl group and hence undergo weak intermolecular association due to dipole-dipole interactions between the opposite ends of the c=o dipoles. the dipole-dipole interactions are however weaker than intermolecular hydrogen bonding between alcohol molecules.
4.Hydrocarbons are highly volatile of all the compounds.because they have weak intermolecular forces called dispersion forces.as the no of carbon in the hydrocarbon increases,the strength of the intermolecular forces increases thus boiling point also increases which is why decane is less volatile than hexane.

Which compound/s (water, acetone, ethanol, hexane, decane, 1-decanol, sodium chloride, and/or iodine) do you think will be soluble in hexane and explain why. You must discuss intermolecular forces in your explanation.
2. Identify the strongest type of intermolecular forces in acetone, ethanol, water and hexane. (Structures listed on page 15.) Experiment 2 Intermolecular Forces There are three general types of intermolecular forces. All substances exhibit London Dispersion Forces (LDF), and they are generally the weakest of the three types. These London forces are due to the attractions between small, temporary dipoles that arise from the constant, random movement of the electrons in a substance. As molar mass increases, the size of...
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...
