Explain recrystallize a compound in boiking hexanes

Reference no: EM13274311

You are attempting to recrystallize a compound but it won't dissolve in boiking hexanes and while it readily dissolves in boiling ethyl acetate, no crystals are formed upon cooling. What is the problem and what would be your next choice of a single solvent to perform the recrystallization
