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.

What effect does recrystallization expected to have on the melting point of your product? Briefly explain why. I know that recrystillzation is a method to purify a desired product and depending how well or poor the process was done, it will affecting the melting point range. So if the recrystallization product is done well, then the melting point range will be very small indication that the desired product is near pure and vice versa. However, I can't seem to figure...
