The dopamine molecule is capable of making strong hydrogen bonds. Edit the dopamine molecule so that you create a new molecule that no longer can make strong hydrogen bonds

Question

anonymous · Answer

Hydrogen bonds can be easily formed, when a Hydrogen molecule is bonded with either an Oxygen, or a Nitrogen molecule, 

but NOT when hydrogen is bonded with Carbon. 

If you can change any of the Oxygen-Hydrogen bonds, or Nitrogen-Hydrogen bonds, into Carbon-Hydrogen bonds, 
then you'll eliminate the places where hydrogen bonds can happen.
