4.2. Hydrophobicity and Organic Compounds

Try these first

1. 1.

   What does hydrophobicity mean?

   Hint

   Think of compounds that don't mix with water.

2. 2.

   Give an example of an organic compound that is hydrophobic.

   Hint

   They float on water.

3. 3.

   What does hydrophobicity mean?

   • Water-loving
   • Water-fearing
   • Water-soluble

   Hint

   Think about substances like oil.

4. 4.

   Which type of compounds typically has higher solubility in water?

   • True
   • False

   Hint

   Consider salts and ions.

5. 5.

   Consider a water sample containing both sodium chloride and long-chain hydrocarbons. Describe how you would separate each and explain the methods used.

   Hint

   Consider the state of materials in water.

6. 6.

   How would you design an experiment to measure how the presence of functional groups affects the solubility of organic compounds?

   Hint

   Think about controlling variables and ensuring reproducibility.
