← ScienceWhich risk increases when asymmetric molecular bond vibrations weaken attraction?
A)Increased infrared radiation absorption✓
B)Decreased chemical reaction activation energy
C)Enhanced dipole-dipole intermolecular forces
D)Reduced nuclear magnetic resonance activity
💡 Explanation
Increased infrared absorption occurs because weaker bonds enhance **resonance**. Resonance allows vibrational modes to couple more effectively with approaching infrared photons. Therefore absorption increases, rather than decreased activation energy because stronger bonds hinder reactions.
