Question

I have a question regarding organic chem lab

Answer 1

this is the question

Answer 2

The silica column is polar, so the eluting solvent will be of a more non-polar nature, therefore non-polar molecules will interact more strongly with the eluting solvent more than the column. So the most polar will be elute last and the most non-polar will elute first.

Answer 3

how would i know if something is polar?

Answer 4

from the functional groups present and the geometry of the molecule

Answer 5

look for permanent dipole moments

Answer 6

thanks

Answer 7

no problem

Answer 8

cant figure out whats wrong

Answer 9

that's not the right order.

the most non-polar is the one that is a hydrocarbon, then the aromatic ring, then the alcohol and then the acid
