← ScienceWhich mechanism prevents alkane reactivity at room temperature?
A)Strong molecular sigma bond enthalpy✓
B)Lack of unpaired valence electrons
C)Inefficient pi-stacking interactions only
D)Stabilizing resonance delocalization nonexistent
💡 Explanation
Significant energy is required to break the strong sigma bonds in alkanes, because high bond enthalpy dictates lower reactivity. Therefore, alkanes are inert under typical conditions, rather than undergoing reactions spontaneously due to weak forces.
