A 0.1 M solution of an enantiomerically pure chiral compound D has an observed rotation of 10.20
Question:
A 0.1 M solution of an enantiomerically pure chiral compound D has an observed rotation of 10.20° in a 1 dm sample container. The molecular mass of the compound is 150.
(a) What is the specific rotation of D?
(b) What is the observed rotation if this solution is mixed with an equal volume of a solution that is 0.1 M in L, the enantiomer of D?
(c) What is the observed rotation if the solution of D is diluted with an equal volume of solvent?
(d) What is the specific rotation of D after the dilution described in part (c)?
(e) What is the specific rotation of L, the enantiomer of D, after the dilution described in part (c)?
(f) What is the observed rotation of 100 mL of a solution that contains 0.01 mole of D and 0.005 mole of L? (Assume a 1 dm path length.)
(g) What is the enantiomeric excess (EE) of D in the solution described in part (f)?
