Question
  1. Why is Wurtz reaction is carried out in dry ether?
  2. Why do alkene have higher boiling point than alkane?
✓

Answer

  1. Sodium metal reacts with water, therefore, dry ether is used in Wurtz reaction. Alkyl halide are soluble in dry ether.
  2. Alkenes are more polar than alkanes therefore, have more van der Waals forces of attraction, hence higher boiling point.
