  •  
    • State 5 physical properties of ethane
    • Low melting and boiling point
    • Low density
    • Not soluble in water
    • Soluble in organic solvent
    • Cannot conduct electricity
  • Chemical properties of alkanes (20 m) a) Write chemical equation for complete combustion of methane Correct reactant = 2m Correct product = 2m
  • Write BOTH STRUCTURAL AND MOLECULAR equations for substitution reaction of methane
    • Step 1
    • CH 4 + Cl 2 ---------> CH 3 Cl + HCl
    •                  
  • step 2 CH 3 Cl + Cl 2 -------> CH 2 Cl 2 + HCl             
    • Step 3
    • CH 2 Cl 2 + Cl 2 ---------> CHCl 3 + HCl
    •                  
  • step 4 CHCl 3 + Cl 2 -------> CCl 4 + HCl              Cl Cl
