the solubility of a compound with a melting point of 65°c is as follows: 8 g/100 ml hexanes (68˚c), 1 g/100 ml hexanes (0˚c). if you tried to recrystallize 1 g of this compound from 10ml of hexanes, you would notice an oil forming in the hot mixture. what is this oil? what would you do to correct the problem so that the compound will recrystallize properly?
