Describe in detail (you can use a sketch with numbers)
how you could distinguish between the ISOMERS of diisopropyl ether
and dipropyl ether using HNMR AND CNMR.
Can you distinguish between absolute changes and percentage
changes in the financial statement numbers? Which is a better
measure of change? How do you tell?
Tell how you could distinguish chemically between the following
pairs of substances (in separate test tubes) in one or two steps.
In each case, tell what you would observe. Include equations for
reactions occurring. NaCl and NaNO3 solutions. KI and Na2SO4
solutions. KNO3 and K3PO4 solutions. BaCO3 and Ba(PO4)2 solids.
How could you distinguish between the following pairs using
hydrogen NMR?
cyclohexane and benzene
butane and 2-methylpropane
butyne and 1,3-dimethylbutane
ethanol and dimethyl ether
How could you distinguish between the pairs of compounds in
question 1 using carbon NMR?
How can you use motivation theory in the workplace? How could
you use motivation theory to design employment policies which would
increase or sustain employee motivation? Give specific
examples.
How do you distinguish between data, knowledge, and wisdom? How
do you distinguish between tacit knowledge and explicit knowledge?
Provide some examples of how businesses use these concepts and how
you have personally used these concepts.
1.Explain how you could use the simple laboratory tests
performed in this experiment to distinguish bet the following
compounds

b. 3-pentanone and pentanal
c. Benzalehyde and acetophenone
d. Acetaldehyde and propionaldehyde
2. In the separation of t-butyl chloride from the reaction
mixture, what is the purpose of the following washes?
a. cold water b. sodium bicarbonate c. water
3. Benzyl chloride, though a primary halide, readily forms a
precipitate when treated with 2% ethanolic silver nitrate....
