76. How can we explain the fact that CCl4 is a liquid and CL. is a solid at 25℃? Which of the followingoptions is the best explanation?
(A) CCl4 has a larger dipole moment than Cl4 due to the higher electronegativity of CI compared to I.
(B) Cl4 has a larger dipole moment than CCl4 because there is stronger electron repulsion in the Cl-I bonds than in the C-CI bonds.
(C) London dispersion forces are stronger in C Cl4 than in  Cl4 because Cl is more electronegativethan I.
(D) London dispersion forces are stronger in  Cl4 than in C Cl4 because  Cl4 has a more easilypolarizable electron cloud.
(E) None of the above.
