Differences Between Methanol And Water

. Our predictions were not supported by our data. We predicted Hexane to not mix well with the other liquids, due to the fact that is a nonpolar substance. When in fact it mixed with all but two substances , Methanol and Water. I believe this to be for the fact that both Methanol and water have strong properties of hydrogen bonding. While we thought water wouldn't mix , we predicted Dichloromethane , n-Pentanol,Methanol,Toulene and Water to mix. Again our predictions were not exact in that water did not mix with any of the substances except Methanol. This again was due to water's strong properties of hydrogen bonding, resisting to interact with molecules that do not also have strong properties of hydrogen bonding. While n-Pentanol is capable of hydrogen bonding, in reference to it's size the majority of the molecule does not hydrogen bond, where as Methanols ability to hydrogen bond is significant in reference the molecules small size.

2. Methanol was the only substance that NaCl would not completely dissolve in. Water is the only substance that completely dissolved NaCl. NaCl is formed by an ionic bond, meaning it has strong Ion-Dipole forces. Water can dissolve NaCl because the slightly positive Hydrogens found within …show more content…
Dichloromethane and Methanol were able to completely dissolve Benzoic acid. However Hexane was unable to completely disolve Benzoic acid. Dichloromethane was able to completely dissolve Benzoic acid , due to both molecules being nonpolar. Benzoic acid has a is made up of a carbon ring which is nonpolar and is easily dissolved by the nonpolar molecule dichloromethane. Methanol also dissolved Benzoic acid, due to dipole-dipole intermolecular forces and hydrogen bonding between both molecules. Our predictions were acurate with Dichloromethane and Benzoic acid, but not we were incorrect in reference to water and Benzoic acid. Benzoic acid would not dissociate in water because a large portion of the molecule is nonpolar while water is
