symmetry elements and point groups
Exercise 1:
The molecule CH3Cl is of C3v symmetry. What are
the symmetry elements of this point group and where are they located in
CH3Cl ?
Exercise 2:
What is the point group of the following bodies:
a) a isosceles triangle,
b) a equilateral triangle,
c) a (round) pen before it is sharpened,
d) a sharpened pen,
e) a propeller with three flat vane,
f) a (typical) table,
g) a human (idealized)?
Exercise 3:
Determine the symmetry elements and the point group of the following
molecules:
NO2 (bend), CH3Cl, CCl3H, CH2=CH2,
cis-CHCl=CHCl, trans-CHCl=CHCl, naphthalene, chlorbenzene.
