(b) Do compounds of hydrogen exhibit a relatively large or small kinetic isotope effect? Explain.
joja [24]

Compounds of hydrogen exhibit a relatively large kinetic isotope effect.

The phenomenon known as the kinetic isotope effect (KIE) is brought on by the variable reaction speeds that are displayed by isotopically substituted compounds. When it comes to studying reaction kinetics, mechanisms, and solvent effects, isotope effects like KIEs are invaluable tools in both physical and biological sciences.

The phenomenon known as the kinetic isotope effect (KIE) is brought on by the variable reaction speeds that are displayed by isotopically substituted compounds. When it comes to studying reaction kinetics, mechanisms, and solvent effects, isotope effects like KIEs are invaluable tools in both physical and biological sciences. The replacement of hydrogen with deuterium is a highly frequent isotope substitution. The ratio kH/kD, which describes this as a "deuterium effect," is used to measure it. Due to the proportion, significant effects are observed.
