Lab 5.
Prelab Questions.
Questions you NEED
to answer in a written form before the Lab. The
answers should be reported in your notebook.
- Draw resonance
structures for dye C.
- What is the number of p
electrons in the free electron system for dye C? Make an
energy level sketch for dye C.
- How many nodes are in Y5, the wavefunction where n =
5, in Y6?
- Presuming that the
extinction coefficient of a dye at a wavelength of
observation equals e = 50,000 M-1cm-1,
calculate its concentration in order to observe the
absorbance A = 1.0 in a 1 cm cuvette.
- Calculate the amount
of NaCl needed for making 1.0M solution in 2mL volume.
What kind of questions you MAY be
asked before the Lab.
Solve the Schrödinger equation
for a particle in a box- Why in majority of cases color arises from motion of
electrons?
- Which molecules are likely to better fit the particle in
a box decription:
