Dipole moment gives an idea about bond polarity. It is a result of differences in electronegativities of elements forming a covalent bond.


The given molecule XCl2 has a dipole moment, so it must be a polar molecule.


To solve this problem, we will:

  • Draw Lewis dot structures for both BeCl2 and SCl2
  • Determine the structure of molecules
  • Check to see which one is polar
