Respuesta :
The highest boiling point is of CH₄. CH₄ has highest boiling point because CH₄ has large value of molecular weight as compared to H₂.
The edge of boiling over of a substance is the temperature at which the fume tension of a fluid equivalents the strain encompassing the liquid and the fluid changes into a fume.
The edge of boiling over of a fluid fluctuates relying on the encompassing ecological strain. A fluid in a fractional vacuum has a lower edge of boiling over than when that fluid is at barometrical strain. A fluid at low strain has a lower edge of boiling over than when that fluid is at climatic tension.
Along these lines, water bubbles at 99.97 °C (211.95 °F) under standard tension adrift level, however at 93.4 °C (200.1 °F) at 1,905 meters (6,250 ft) height. For a given tension, various fluids will bubble at various temperatures.
Boiling point is directly proportional to the molecular weight of the compound. Since CH₄ molecular weight is 16 g/mol whereas H₂ has molecular weight of 2 g/mol, therefore intermolecular force is more in CH₄.
