Pen ink has made a chromatography pattern becaues it has 3 different dye's in it. How can I tell which dye has the most "hooks" in it?

What do you mean by "hooks". Need more information. What type of chromatography, solevents, etc.

Well, Well, Well!!! Yet another homework
assignment I suspect!! Rob, am I right in
thinking that "hooks" is an analogy used by
your teacher to explain the way that some of
the dyes travel further up the paper than
others? If I am right in my assumptions, and
hooks is not some new HPLC technique I've
not come across, I will try to point you in the
right direction. However, I will not answer the
question for you.

By saying that the dyes have hooks, indicates
that there is some way in which the
molecules grip to the chromatography paper.
You have to think about how the number of
"hooks" the dye has relates to how fast it will
run up the paper.

Clue- What would be the fastest dye up the
paper, one with hooks, or one without?

Also, bear in mind that the dyes do not realy
have little hooks in them!!!

Good luck!

Ok Will, if chelating agents can have claws, why can't dyes have hooks? How else are you going to get the dye to stick to a wool garment?
