Hydrogen bonds

Post by hplc » Mon Sep 29, 2008 4:29 pm

Hey

There is a task in my textbook I need help with.

"Draw all possible hydrogen bonds for the two molecules below. Both between similar molecules, and between one on each kind."

Picture of the two molecules are below. I hope you can help me.

Thanks.

Well to do this question you need to have knowledge of which atoms bonded to Hydrogen actually cause Hydrogen Bonding. In this particular case you have only two such atoms, and they have both been identified for you in both molecules.

I know which atoms can participate in hydrogen bonds, but I don't understand how I'm supposed to do this task. Say from Nitrogen; Am I supposed to draw a hydrogen bond to a OH-group that I make somewhere, for instance?

you don't have to make an oh group. There's one in your diagram already.
