Which of the following compounds has the highest boiling point, HF, CH4, PH3, H2S, or H2O? 🥇



The scientific explanation to this would be ‘of course water, because it is a strong dipole with hydrogen bonds’. But you can answer this question even without googling boiling points for each of those. Of all the mentioned chemical compounds, only water is liquid at room temperature (below its boiling point, as boiling point is where a compound goes from liquid state to gas state). The rest are gases when at room temperature so their boiling point is obviously below that of water.

It’s easy!
