Benzophenones nonionic nature makes it in meltable with urine (which is polar), meltable with wood inebriant (which is of intermediate polarity) and soluble with hexane (which is nonionised). This is because generally, exchangeable dissolves like nonpolar leave dissolve nonpolar precisely non polar, and vice versa. just now note that this is an feeble science you would expect hexane to dissolve quicker 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 molecule, making it a little polar, although mostly nonpolar. Biphenyl, which is completely nonpolar, leave have similar solubilities as benzophenone water- water-insoluble with water (polar), partially soluble with methanol (intermediate polarity) and soluble with hexane (nonpolar). But with biphenyl (unlike with benzophenone) the solubilities ar on the nose as expected, because of biphen yls complete nonpolarity.But that explains any differences in solubilities in the midst of the two molecules. Polarity similarly played a role in the alcohol reactions water, which is polar, get out be insoluble with I-octanol (which is nonpolar), insoluble with I-butanol (also nonpolar), and soluble with methanol (polar). But its a little more alter the hundred chain of each of these thoroughgoing compounds will always be nonpolar and whence 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 defend a smaller hydrophobic draw out and the overall molecule will therefore be hydrophilic. The hexane-alcohol reactions had the opposite solubilities, due to hexanes nonpolar nature (and the rule of like dissolves like) soluble with I-octanol (nonpolar), soluble with I-butanol (nonpolar), and insoluble with methanol (pola
