  • question_answer Boiling point of ethane is more than that of methane. Assign reason.

    Answer:

                    The molecular size of ethane \[(C{{H}_{3}}-C{{H}_{3}})\]  molecule is more than that of methane\[(C{{H}_{4}})\]. Therefore, the van der Waals forces of attraction are more in ethane molecules than in molecules of methane resulting in higher boiling point.
