If a strong external electric field is applied to carbon nanotubes functionalized with highly electronegative fluorine atoms, which consequence follows?

A)Increased metallic conductivity arises
B)Induced dipole enhances field emission
C)Decreased tube structural stability results
D)Quantum confinement effects diminish

💡 Explanation

The external field induces a significant dipole moment in the fluorine-functionalized carbon nanotube because the highly electronegative fluorine atoms draw electron density, creating charge separation. Therefore, this induced dipole enhances the electron field emission due to localized field enhancement, rather than altering conductivity or stability without defects.
