Vedclass · Answer

(C) Deuterium $(D)$ is an isotope of hydrogen $(H)$. Due to the higher mass of the deuterium nucleus compared to the hydrogen nucleus,the bond dissociation energy of $D-D$ or $D-X$ bonds is generally higher than that of $H-H$ or $H-X$ bonds. This leads to a kinetic isotope effect where the reaction involving deuterium proceeds at a slower rate than the corresponding reaction involving hydrogen.
