← ScienceWhich outcome occurs when a moderate electrical field is applied to crystalline sodium chloride?
A)Ionic conductivity increases with rising temperature✓
B)Covalent bond formation produces a transient charge
C)Hydrogen bonds facilitate swift proton transfer
D)Molecular orbitals become significantly destabilized
💡 Explanation
Ionic conductivity increases with temperature because the increased thermal energy enhances ion mobility via the Vacancy mechanism through crystal lattice defects. Therefore, ionic conductivity rises rather than molecular orbital changes, bond forming, or any hydrogen bond impacts.
