Question
1. Theoretical questions
a. If two compounds have the same Rf under identical TLC conditions, does that mean they
have identical structures? Explain.
b. Can a mixture of d- and l-carvone be separated by column chromatography on silica gel
using hexanes/acetone as the elution solvent? Explain.
c. Would it be possible to separate carvone and limonene using just hexanes as the eluent
(never switching to the 10% acetone in hexanes mixture)? What would be the result if you
tried? Explain. |
