All3 (Aluminium Iodide) is electrically a _
Correct answer: B. Non - conductor
- A. Conductor
- B. Non - conductor
- C. Semiconductor
- D. None of these
Explanation
A non-conductor, also known as an insulator, is a material that does not allow electric current to flow through it easily. Aluminium iodide is not typically considered a non-conductor, as it can conduct electricity to some extent when dissolved in water. It does not conduct heat or electricity, as its a covalent compound.

About Ionic and Molecular Crystals
Ionic crystals contain oppositely charged ions held by electrostatic forces, whereas molecular crystals contain discrete molecules joined by weaker intermolecular forces. Their structures explain differences in melting point, hardness, volatility, solubility and electrical conductivity, especially between solid and molten states.
