Question

Increasing order of bond energy of different isotopes of hydrogen is ​

Answer 1

Answer :

The increasing order of Bond length is Ethyne < Ethene < Ethane. Bond length is inversely proportional to the bond dissociation energy. This means that more will be the bond length less will be the bond dissociation energy.

Answer 2

Bond energy is the strength of chemical bond

Explanation:

• Bond energy is also known as bond enthalpy.
• It is the entity which define the strength of chemical bond.
• Bond energy is directly proportional to the stability of the bond.
• Greater the bond energy greater will be the stability of chemical bond.
• Hydrogen has three isotopes they are Protium ¹H₁.

Deuterium ²H₁ or D

Tritium ³H₁ or T

The mass ratio of Protium,Deuterium andTritium is 1:2:3

Increasing order of bond energy of different isotopes of hydrogen is ​Protium > Deuterium >Tritium
