3.12.2 We perform an experiment in which we prepare a particle in a given quantum mechanical stat e and then measure the momentum of the particle. We repeat this experiment many times and obtain an average result for the momentum (p) (the expectation value of the momennum) For each of the following quantum mechanical states, give the (vector) value of (p) or, if appropriate.

1. Draw the two stereoisomeric products from the following
reaction, which uses a single enantiomer (i.e. optically active
compound) as the starting material.
2. Write a detailed reaction mechanism for the reaction.
3. Determine the R/S configuration for the original chiral
center and any new chiral centers formed in the reaction.
4. Comment upon whether a 1:1 mixture of the two compounds in
part 1 would be optically active.

What is/are constant(s) within an experiment? Select one: a. Response (dependent) variables which must be kept the same throughout the experiment. b. Any variable, other than the explanatory (independent) variable, which is/are kept the same between treatments. c. Variables, other than the response (dependent variable), which are varied throughout the experiment. d. Explanatory (independent) variables which require controls.
