Order the following compounds from lowest to highest boiling point: SnCl₄, SnBr₄, SnI₄. A) SnI₄, SnBr₄, SnCl₄ B) SnCl_4, SnBr₄, SnI₄ C) SnBr_4, SnI₄, SnCl₄ D) SnCl_4, SnI₄, SnBr₄ E) SnI₄, SnCl₄, SnBr₄

Question

Quizplus · Accepted Answer

The boiling points of compounds increase with the size and mass of the halogen atom due to stronger London dispersion forces. Therefore, SnCl2 (with chlorine) has the lowest boiling point, followed by SnBr2 (with bromine), and SnI2 (with iodine) has the highest boiling point.
