← ScienceWhich mechanism causes increased reactivity in strained cyclic molecules maintaining pi orbitals?
A)Bent bond hybridization weakening overlap✓
B)Enhanced resonance through sigma donation
C)Improved leaving group departure kinetics
D)Increased entropy due to ring flexibility
💡 Explanation
When cyclic molecules are strained, bent bond hybridization occurs because the bond angles deviate from optimal sp3 geometries, leading to less effective orbital overlap and weakened bonds. Therefore bent bond hybridization increases reactivity, rather than enhanced resonance, improved leaving group departure, or entropic factors.
