Molecules and the bonds between atoms can also have polarity. Answer: CH2Cl2 is a polar molecule due to the unequal distribution of charge caused by the pull of electrons from the hydrogen atoms to the chlorine atoms due to hydrogen (2.20) have a lower electronegativity than chlorine (3.16). Molecules are only non-polar if they contain no polar bonds or if the partial charges cancel out each other. Freon-2 (CF2Cl2) Polar or Nonpolar (based on characteristics) CF2Cl2 is a polar molecule and the Fluorine atom closest to the negative side as fluorine is highly electronegative than both chlorine and carbon. WIth this as a basis, account for the difference between the dipole moments of CH2F2 and CF4. Toluene. (i), Which of the following statements is (or are) true? Polarity in a molecule occurs due to the unequal sharing of valence electrons; since theres no unequal sharing of valence electrons in the case of carbon dioxide, it is nonpolar.
