← ScienceWhich outcome occurs when high-energy radiation affects molecular hydrogen?
A)Dissociation yields free radicals✓
B)Ionization ceases chain reactions
C)Increased bond vibrational frequency
D)Stable noble gas compound forms
💡 Explanation
High-energy radiation causes homolytic bond cleavage, initiating **dissociation** and forming highly reactive hydrogen radicals because this process overcomes the bond's energy threshold. Therefore, radicals arise, rather than ionization stabilization, due to low ionization potential of hydrogen molecules.
