Question
In the separation of t-butyl chloride from the reaction mixture, what is the purpose of the following washes? Cold water: Sodium bicarbonate: Water: In the separation of n-butyl chloride from the reaction mixture, what is the purpose of the following washes? Concentrated sulfuric acid: Water: Sodium hydroxide: The addition of anhydrous calcium chloride to the crude product obtained from the separation procedure often results in the product becoming clear (transparent). What causes this clearing? Benzyl chloride, though a primary halide, readily forms a precipitate when treated with 2% ethanolic silver nitrate. Explain.Explanation / Answer
a)
Cold water --> all salts & cooling
b)
sodium bicarbonate --> reaction of acid to form salts and carbonates
c)
water --> clean all ions such as Na+ and other
Q2
a)
sulfuric acid -> neutralization of bases/carbonates
b)
water --> get rid of aquous salts
c)
Na(OH) --> neutralization of acids to form the respective salt for extraction
Q3
the clearing is essentially the increased solubility of the specie due to the Ca and Cl- ions... t
Q4
Benzyl Chloride will form prcipitates, since Ag and Cl- are present
