Exercise 1:
a) Determine the point groups symmetry of the following molecules in their electronic ground state: H2O, acetylene C2H2, ethylene C2H4, ethane C2H6, methylfluoride CH3F, benzene C6H6.
Exercise 2:
a) Work out by yourself the multiplication table for the set of operations C2v.b) Explain the following statement: An object having a rotational-reflection axis Sn, where n is odd, must necessary also have a Cn axis coinsiding with the Sn axis and a symmetry plane σh perpendicular to the Sn axis. Is this statement correct for even values of n?
