Benzophenones nonpolar disposition makes it insoluble with piddle (which is polar), soluble with methanol (which is of intermediate polarity) and soluble with hexane (which is nonpolar). This is because generally, exchangeable dissolves kindred nonpolar go out dissolve nonpolar but not polar, and criminality versa. But note that this is an imperfect science you would expect hexane to dissolve instant(prenominal) and more completely than methanol (because of the differing polarities), but the opposite occurred.This may be ecause of benzophenones ketone group, which adds a slight polarity to the whit, making it a little polar, although in general nonpolar. Biphenyl, which is completely nonpolar, pass on have similar solubilities as benzophenone insoluble with water (polar), partially soluble with methanol (intermediate polarity) and soluble with hexane (nonpolar). But with biphenyl (unlike with benzophenone) the solubilities are barely as expected, because of biphenyls compl ete nonpolarity.But that explains any differences in solubilities between the two molecules. preindication also played a role in the alcohol reactions water, which is polar, will be insoluble with I-octanol (which is nonpolar), insoluble with I-butanol (also nonpolar), and soluble with methanol (polar). But its a little more complicated the carbon ambit of each of these perfect compounds will always be nonpolar and therefore hydrophobic, but as these are alcohols, the -OH group, which is polar and therefore hydrophilic, comes into play as well.So its kind of a battle between the hydrophobic carbon chain and the ydrophilic alcohol group, and when the chain is long, as in octanol, it will overpower the alcohol. Conversely, in small alcohols like methanol (or ethanol etc. ), where the carbon chain is much shorter, it will exert a smaller hydrophobic force and the overall molecule will therefore be hydrophilic. The hexane-alcohol reactions had the opposite solubilities, due to hexane s nonpolar nature (and the rule of like dissolves like) soluble with I-octanol (nonpolar), soluble with I-butanol (nonpolar), and insoluble with methanol (pola
