Question 2

The boiling point of 1,4-butanediol is 230C. Would you expect this compound to be soluble or insoluble in room-temperature water?
 
  A) Since there are no polar areas on this molecule, it is insoluble in water at room temperature.
  B) A high boiling point means that the substance interacts with itself quite strongly. Therefore this molecule is not soluble in water.
  C) Since there are polar areas on this molecule, it is insoluble in water at room temperature.
  D) Water would be attracted to both ends of 1,4 butanediol, and it is infinitely soluble in water.
