So i'm not quite sure exactly what the limitations are going to be drawing a tlc plate in chemdraw, as i've never done that, but we can draw a tlc plate that is representative of these particular compounds knowing their rf values.
00:21
If we have a solvent front that travels this distance, then an rf value for transcinemic acid.
00:32
Of 0 .27 means it's traveled.
00:36
0 .27 of the distance the solvent front traveled.
00:41
So if this is the line where we spotted it and we'll just arbitrarily, not arbitrarily, but do a dotted line here for halfway up, that would be 0 .5.
00:56
Then 0 .27 is going to be a little bit more than halfway to halfway.
01:04
So this would be transcinamic acid.
01:19
Menthal would have an r value of 0 .64, so it would be 0 .64 up to the solvent front.
01:28
So it would probably be about here.
01:36
So menthol.
01:41
And then isovanillin is 0 .2...
