D Question 8 10 pts Recrystallization can never be used to purify a compound if the impurity has similar solubility as the desired compound True False DQuestion 9 10 pts What is taxol?

The yellow cars that will drive you around a city A method of recrystallization for isolation of pure compounds on a small scale using a Craig tube. OA synthetic cancer drug developed by NCI (National Cancer Institute) which is puriñed via recrystallization. DQuestion 10 10 pts What is preferred a fast or slow recrystallization and why? ce and will in turn keep other chemicals from crystallizing, as Slow recrystallization allows a single crystal to form. This single crysta will induce identical crystals to form into a crystal at other chemicals won't fit into the crystal lattice. Fast recrystallization to increase percent recovery. Fast recrystallization to reduce purification time. Slow recrystallization is as effective as fast recrystallization as long as the flask is not so hot it will shatter in the cold ice.Explanation / Answer
1. Recrystallization can be used to purify a compound if the impurities have similar solubility as the desired cimpound.
2. Taxol is a natural product isolated from the bark of the yew tree which is used to treat cancer.
3. Slow crystallization is preferred as it allows a single crysrcr to form. This single crystal will induce identical crystals to form into a crystal lattice and will keep other chemicals from crystallizing as other chemicals won't fit in crystal lattice.
