1. Explain why this reactiob is not carried out in water as a solvent.
2. Does the attached IR spectrum of the product show any evidence of the decomposed by product? Why or why not?
Homework Answers
(a) C6H5SO2 does not react with water.
(b) A step-scan fourier transform spectrometer together with a multipass absorption cell can record the IR Spectra of reaction intermediates formed in this reaction. Two bands with origins at 1087.7 and 1278.2 cm-1 are assigned to SO2 symmetric and anti symmetric stretching modes. The attached Infrared spectrum of the reaction intermediates is thus an evidence of the decomposed by products.

Multistep Synthesis: Synthesis of Amine (Organic Chemistry
Lab)
Question
1. Explain each step of reaction mechanism. (How does it
work?)
2. Discuss reason for reaction sequence. (Why must one reaction
occur before another?)
3. Explain how IR supports the major product.
Experiment Procedure
Imine Formation:
Weigh a 20 mL beaker and then add 380 mg of ortho-vanillin and
268 mg of para-toluidine. Care should be taken to add equivalent
molar amounts of the two reactants.
Observe the mixture and record...

Question 2 (10 marks) Decide how each of the following transactions, if they were carried out, would affect HK GDP. Determine which expenditure component(s) would be affected, if any. If the transactions would not affect HK GDP, explain why. (a) The Hong Kong Police Force are set to receive HK$25.8 billion from the 2020 government budget! They plan to use HK$21.9 billion to increase its police force by 2,543, which is the biggest manpower boost since 1997. They also plan...

2. *D1* Salt water is plentiful on earth; natural supplies of fresh water, on the other hand, are dwindling while mankind's demands grow. One appealing solution to this imbalance is to remove the salt from ocean water by some means. Here you will investigate the energy input that is necessary to accomplish this task. Special membranes can be manufactured that allow water, but not ions, to pass through. By pushing such a membrane through salt solution, one can separate salt...
