Pyrrolidine is a much stronger base than pyrrole. Explain
One knows that the Beer-Lambert law, expresses the relationship of the
spectrophotometric absorbance (Abs) of a solution of a compound to the
concentration(c) and light path length (l) of the sample. The
proportionality constant, when the solution concentration is in M, is
called the molar extinction coefficient (E). One would like to
determine the molar extinction coefficient (E) of a “newly discovered
compound”. One places 3.00 mL of a solution that is 5.37 x 10^-6 M in
a 1 cm^2 cuvette. The absorbance that one measures is .863. What is
the extinction coefficient? And just to be sure what are the units of
the molar extinction coefficient (E)?
