Which outcome occurs when a platinum catalyst activates molecular hydrogen?

A)Heterolytic splitting forms protic species
B)Homolytic cleavage forms hydrogen radicals
C)Hydrogen molecules remain entirely intact
D)Dehydrogenation results eliminating all hydrogen

💡 Explanation

Heterolytic cleavage occurs via oxidative addition splitting into a proton and hydride because the metal-hydrogen interaction stabilizes charge separation; therefore, the activated hydrogen becomes polarised rather than producing radicals under normal catalytic conditions due to high activation energy barriers.
