← ScienceWhich outcome occurs when overlapping p-orbitals form pi-bonding molecular wave functions in benzene?
A)Increased electron delocalization across the ring✓
B)Enhanced vibrational modes in the molecule
C)Reduced bond length between carbon atoms
D)Suppressed reactivity towards electrophilic attack
💡 Explanation
When p-orbitals overlap to form pi-bonding molecular wave functions, electron density spreads across the entire ring through a process called electron delocalization because quantum mechanics minimizes the electron's potential energy; this lowers the bond energy, leading to increased electronic stability. Therefore increased electron delocalization results, rather than other vibrational, bond length, or reactivity effects, requiring different bonding configurations.
