Arrange the following CaH2, BeH2 and TiH2 in order of increasing electrical conductance.

1 Answer

Solution :-

The electrical conductance of a molecule mainly depends on its covalent or ionic nature. CaH2 is an ionic hydride, which conducts electricity in the molten state. Titanium hydride, TiH2 is metallic in nature and conducts electricity at room temperature.  Covalent compounds do not conduct, whereas Ionic compounds conduct.  BeH2 is a covalent hydride. Hence, it does not conduct.

Hence, the increasing order of electrical conductance is as follows:

BeH2 < CaH2 < TiH2
