Arrange the following CaH2, BeH2 and TiH2 in order of increasing electrical conductance
Ionic compounds conduct electricity whereas covalent compounds does not. BeH2 is a covalent hydride and does not conduct electricity. CaH2 is an ionic hydride and conducts electricity in molten state. TiH2 is metallic in nature and conducts electricity at room temperature. Hence, the increasing order of electrical conductivity is BeH2<CaH2<TiH2.
