Questions:

2. How would the following actions effect both the yield AND the purity of your recrystallized 4-chlorobenzyl alcohol?

a. The dichloromethane extracts containing the crude 4-chlorobenzyl alcohol are not washed with sodium bicarbonate solution before proceeding with the isolation.

b. The dichloromethane extracts are not treated with sodium sulfate before concentration to obtain the crude alcohol.

c. Insufficient solvent is used for the recrystallization of the alcohol, so that it initially precipitates as an oil rather than a solid.

3. How would the following actions effect both the yield AND the purity of your recrystallized 4-chlorobenzoic acid?

a. A single extraction with dichloromethane is performed on the reaction mixture at step 6 instead of three.

b. Insufficient concentrated HCl is added to the aqueous solution of the 4-chlorobenzoic acid at step 11 before filtering out the crude product.

c. The pipet used to transfer the 4-chlorobenzoic acid into the Craig tube in step 4 of the recrystallization of 4-chlorobenzoic acid is not heated beforehand.
