Comparing ethyl chloride and ethyl iodide, the latter has a significantly higher boiling point. Which intermolecular force is primarily responsible for this difference?
Q1. Comparing ethyl chloride and ethyl iodide, the latter has a significantly higher boiling point. Which intermolecular force is primarily responsible for this difference?
Answer: London dispersion
Explanation: Iodine is larger and more polarizable, leading to stronger London dispersion forces; dipole-dipole is tempting but plays a smaller role in heavier halides.
