Question

which isotope of hydrogen has high boiling point
​

Answer 1

Explanation:

Out of the three hydrogen isotopes, the most abundant isotope of hydrogen is protium (i.e. Hydrogen), the next one is deuterium & the least abundant is tritium which is radioactive.

∴ Hydrogen>Deuterium>Tritium (% relative abundance)

Density∝mass

∴ Hydrogen<Deuterium<Tritium (density/gL

−1

)

Also, boiling point & melting point is directly proportional to molecular mass.

∴ Hydrogen<Deuterium<Tritium (Boiling point & Meltting point (K))

Answer 2

protium
