Homework Answers
Solution:
Both toluene and mesitylene are nonpolar in nature. Thus, they elute accordiing to their boiling points.
A lower boiling point liquid eluted first in gas chromatography. Since, molar mass of toluene is lower than mesitylene and therefore posses low boiling point, hence it eluted earlier than mesitylene.

Post Lab Questions: CI MALACHITE GREEN CRYSTAL VIOLET 1. Why does the malachite green dye elute first? What physical properties does it have that affect it's interaction with alumina and how are those different from crystal violet? 2. Write the reaction of crystal violet with 1 equivalent of HC. 3. Why does adding HCI cause crystal violet to elute more quickly? What changes with it's physical properties and how does that property affect it's interaction with alumina?
