← ScienceWhich outcome occurs when applying sustained mechanical stress to crystalline ionic compounds?
A)Increased electrical conductivity via electron delocalization
B)Plastic deformation via dislocation migration
C)Brittle fracture along cleavage planes✓
D)Elastic bending with recovery upon unloading
💡 Explanation
When stress is applied, crack propagation occurs because ionic bonds are strong but directional, and prevent dislocation motion, meaning that fracture occurs following crack initiation. Therefore brittle fracture results, rather than plastic deformation, bending, or increased conductivity which require mobile electrons, polymer chains, or ductile materials.
