Correct Answer: Option (A) — Only 1

Concept & Option Breakdown

Standard Reference Verified
  • Statement 1 is correct: Ionic compounds are polar and dissolve readily in high-dielectric polar solvents like water, but are generally insoluble or poorly soluble in non-polar or weakly polar organic solvents such as alcohols.
  • Statement 2 is incorrect: In the solid state, ions are locked into fixed positions within a rigid crystal lattice and cannot move; hence, solid ionic compounds do not conduct electricity. They only conduct electricity when molten or dissolved in aqueous solution where ions are free to migrate.
