II. Questions:
1. Explain
the effect of the charged rod on a jet of water.
2. What
do you think would happen with a rod of opposite charge? Explain.
3. Place the liquids in an approximate
order of decreasing polarity. Interpret this order in terms of the structure of
each molecule and comment particularly on the different results in the
following pairs.
(a) trichloromethane, CHCl3, and
tetrachloromethane, CCl4;
(b) cyclohexane, C6H12,
and cyclohexene, C6H10.
