FREE Expert Solution

Recall that the main idea in dissolution is like dissolves like, which means compounds with the same polarity and intermolecular force can dissolve each other.


Water (H2O) is a polar molecule that exhibits hydrogen bonding.


Alcohols are soluble in water. 

  • This is due to the hydroxyl group (-OH) in the alcohol which is able to form hydrogen bonds with water molecules. 
  • This means all of them are soluble in water.
