Which outcome results when electron orbitals overlap in conjugated polymers?

A)Enhanced electron delocalization occurs.
B)Band gap energy increases sharply.
C)Coulomb repulsion approaches zero.
D)Electron tunneling becomes impossible.

💡 Explanation

Since overlapping orbitals allow electrons to spread across the molecule via electron delocalization, increased conductivity occurs because pi-electrons move freely. Therefore enhanced delocalization is correct, rather than increased band gap, which needs stronger input.
