Question
- Which of the following best helps to explain why CCl4 is a liquid whereas CI4 is a solid when both are at 25°C?
A.
The dipole moment of the CCl4 molecule is larger than that of the CI4 molecule because Cl is more electronegative than I .
B.
The dipole moment of the CI4 molecule is larger than that of the CCl4 molecule because there is stronger repulsion between electrons in the C−I bonds compared to the repulsion between electrons in the C−Cl bonds.
C.
The London dispersion forces are stronger in CCl4 than in CI4 because Cl is more electronegative than I .
D.✓ Correct
The London dispersion forces are stronger in CI4 than in CCl4 because CI4 has a more polarizable electron cloud than CCl4.
