Homework Statement


I have a methyl orange molecule.

Then my problem says that "wool is a protein, a naturally occurring polymer made up of amino acids with ionized side chains. cotton is a naturally occurring polymer made up of glucose units with hydrophillic groups surrounding each glucose unit. nylon is a synthetic polymer made of hydrocarbon repeating chains joined together by highly polar amide groups."

Using this hypothesis, predict the relative color intensity that would be produced by methyl orange on cotton, nylon, and wool from least to greatest.

Homework Equations



no equations

The Attempt at a Solution


[/B]
So I believe that a H-N bond is less polar than H-O bond, so the hydrogen bonding caused by nylon's amide groups will be weaker than that caused by the glucose's hydrophillic groups. So I believe that the color intensity of cotton > that of nylon.

However, I am confused as to whether amino acids in wool will form more electronegative/polar hydrogen bonds than cotton does and how to rank them.

Please advise on how to solve this problem.

Thanks in advance. Anything is appreciated!

Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?
