Which of the following option is true regarding the boiling point of hydrogen isotopes?(a) all three isotopes have an equal boiling point(b) deuterium has a greater boiling point than tritium(c) tritium has a greater boiling point than that of protium(d) protium has a higher boiling point than that of tritiumThis question was addressed to me by my school teacher while I was bunking the class.This interesting question is from Dihydrogen & H2 in chapter Hydrogen of Chemistry – Class 11

Answer»

The correct answer is (c) tritium has a greater BOILING point than that of protium

Easy explanation: The boiling points of tritium are greater than that of DEUTERIUM and that is greater than that of HYDROGEN. The boiling points in kelvin of hydrogen, deuterium, and tritium are respectively 20.39, 23.67 and 25.
