Question
A researcher isolated 10 g of a Natural Product
from a local plant. In an attempt to determine
the optical activity of this Natural Product, 3.00
g were dissolved in 5.00mL of solvent and
placed into a tube 1.00 cm long. A reading of +
2.22⁰ was recorded.
1. The apparatus used by the researcher to
obtain the reading is called a
2. Write the expression which may be used
to calculate the specific rotation of the
Natural Product. Write out the Greek
names for symbols where necessary
3. Use the expression given above to
calculate the specific rotation of the
Natural Product. Include the appropriate
units and signs..
Part B
Assume that the following measurements are
made in 10cm polarimeter sample containers;
1. A 10ml solution of 0.4 g of optically active
2-butanol in water displays an optical
rotation of -0.56°. What is its specific
rotation?
2. A solution of pure (S) 2-bromobutane in
ethanol is found to have an observed
rotation a=57.3 °. If [a] for (S) 2-
bromobutane is +23.1, what is the
concentration of the solution?
