Given what you know about water and its intermolecular
interactions (from the readings) answer questions 3 and 4.
Assume that the assume that the molecules are flexible.

Q3: Compare the structure of molecule A if each subunit could form hydrogen bonds with water versus the same molecule if subunits are unable to hydrogen bonds with water. 

Assume that the subunits are hydrophobic but that there are positive (red) and negative (blue) charges distributed along its length; how does this influence its structure in water.  
Bring a drawing of your molecule to class and be prepared to present/defend it.
