Re: xylene question
Thank you all for your answers. You've answered my question, and then some. I probably should have been a little more clear with my question to save some explaining. I'm aware of the forms and their chemical structures. I was simply curious as to whether the positioning of the methyl group on the benzene has any affect on its properties as a solvent(eg. maybe a solution with all in the meta position would be a more potent solvent than one with them all in the ortho or para position, therefore I should decrease the time in solvent or be left with brittle tissue to deal with---purely an example--from what I gather solvent characteristics are unaffected by the methyl position). Again, thank you for the promp and thorough answers. I'll go ahead and use the meta without changing the times.
