Does Iodine dissolve in propanone?

Yes, iodine dissolves in propanone (acetone) to form a purple solution. This is because iodine is soluble in nonpolar solvents like propanone due to its nonpolar nature.


What are the chemical tests to distinguish between propanol and propanone benzaldehyde and benzoic acid propanoic chloride and propanoic acid also what are the reactions involved?

To distinguish between propanol and propanone, you can use the iodoform test. Propanone will give a positive iodoform test forming a yellow precipitate, while propanol will not react. For benzaldehyde and benzoic acid, adding NaHCO3 will effervesce with benzoic acid but not with benzaldehyde due to acidity. To differentiate between propanoic chloride and propanoic acid, adding water will form propanoic acid (carboxylic acid) while propanoic chloride (acid chloride) will liberate HCl gas forming a white precipitate. The key reactions involved are iodoform reaction (C3H6O +I2 + NaOH) and acid-base reactions with sodium bicarbonate and water.


Why does propanone has higher vapour pressure than ethanol at room temperature?

The intermolecular forces (IMFs) that attract propane molecules to eachother is far weaker than the IMFs of ethanol molecules. Consequently there is less of an energy barrier for a propane molecule to evaporate. IMFs of propare are limited to the london dispersion forces, which are the weakest IMFs IMFs of ethanol are the london dispersion forces as well as the dipole-dipole interaction (- charge on oxygen and positive on hydrogen) and hydrogen bonding (very strong IMF)
