Question
Hazards (use as much space as necessary)
A. What is the main hazard of diethyl ather?
B. What are the main hazards of 4-nitrotoluene?
C. What are the main hazards of 4-nitrobenzoic acid?
D. Nitrobenzene is much more common that 4-nitrotoluene, and its hazards are better known. Do
you think the hazards of 4-nitrotoluene are likeły to be very different from or very similar to those
of nitrobenzene?
Procedure
(1) Show the reaction between 4-nitrobenzoic acid and sodium hydroxide. (ChemDraw the
structures, and paste below)
(2) Give the density of diethyl ether (simply called "ether") in g/mL:
(3) Give the density of water in g/mL:
(4) Will the density of 5% aqueous NaOH be greater than, less than or the same as that of pure
water?
(5) For a mixture of 20 mL diethyl ether and 20 mL of aqueous 5% sodium hydroxide, two layers
form. Based on densities, which layer is on the bottom?
(6) For ether/neutral water, which layer would 4-nitrobenzoic acid be in mainly?
(7) For ether/neutral water, which layer would sodium 4-nitrobenzoate be in mainly?
(8) For ether/neutral water, which layer would 4-nitrotoluene be in mainly?
(9) How is the 4-nitrobenzoic acid isolated from the basic water solution? (give brief outline)
