Ossih Posted November 1, 2014 Report Share Posted November 1, 2014 Hiya! C8H18 is octane and so is non-polar H2O is polar, because of the shape of the molecule and hydrogen bonding CH4 is methane and so is non-polar Hexane itself is non-polar. Remember, for solubility, we use the rule 'like dissolves like'. So, octane and methane are soluble in hexane, whereas water isn't. Hope this helped 5 Reply Link to post Share on other sites More sharing options...
Msj Chem Posted November 2, 2014 Report Share Posted November 2, 2014 Hexane, methane and octane are members of the alkane homologous series. The alkanes are non-polar molecules. Non-polar substances are soluble in non-polar solvents and polar substances are soluble in polar solvents.Hence the phrase 'like dissolves like'.Methane and octane are both soluble in hexane as they are all non-polar substances.Water is a polar solvent and will dissolve polar substances such as ethanol. 1 Reply Link to post Share on other sites More sharing options...
