Bond length

Vedclass · Answer

(D) Both hydrogen $(H_2)$ and deuterium $(D_2)$ molecules have the same bond length of $74 \ pm$.However, they differ in their physical and chemical properties such as bond energy, melting point, and boiling point due to the difference in their isotopic masses.Based on the data:- Bond length: $74 \ pm$ (Same)- Bond energy: $436 \ kJ \ mol^{-1}$ for $H_2$ vs $443.3 \ kJ \ mol^{-1}$ for $D_2$- Melting point: $0.00 \ ^\circ C$ for $H_2$ vs $3.81 \ ^\circ C$ for $D_2$- Boiling point: $100.0 \ ^\circ C$ for $H_2$ vs $101.42 \ ^\circ C$ for $D_2$Therefore, the bond length is the same.

Which property among the following is the same for both hydrogen and deuterium molecules?
