Multiple Choice Questions

1. Which molecule is most polar by looking at the picture?



  • CH4
  • CH3Cl
  • CH2Cl2
  • CHCl3
  • CCl4



2. Determine the validity of the statement and justify your answer:


CH3Cl has a greater dipole moment than CH2Cl2.


  • True, bond vector is greater because the bond vectors for the two chlorine atoms cancel each other out partly, and thus the partial charge is greater.
  • False, bond vector is greater because the bond vectors for the two chlorine atoms cancel each other out partly, and thus the partial charge is greater.
  • True, because CH2CL2 has greater molar mass.
  • False, because CH2Cl2 has greater molar mass.
