Answer #1

since Ligroin non polar compound always it is preferrable to use a non polar solvent for recrystallization.

What advantages does ethanol have over n-octanol as a recrystallization solvent?

It depends the compound to be used recrystallization. Since compound is non polar it is patially soluble in ethanol and it is good to recrystallization. As well mid polar compounds also. polar compounds are soluble when we use minimum ethanol it is good for recrystallization. But in n-Octanol is a non polar solvent in which mid polar and polar solvents are not soluble. it can not be recrystallized in Octanol.
