Arrange the following in the order of increasing electrical conductance.
O2H2, Hf(II)H2, BeH2, SrH2, CaH2,TiH2,TeH2.
My answer: Electronegativity:- (H)=2.2, Be=1.6, Hf=1.3, O=3.4 Ca, Sr=1,Ti= 1.5
BeH2<TiH2<Hf(II)H2<O2H2=CaH2=SrH2.
Is this answer correct?

Re: Arrangement of chemical compounds in order of increasing electric conductance
I dont think that any compound beside the hydrogen peroxide has an significant conductance, because all are solid. Maybe some can work as semiconductor.

Re: Arrangement of chemical compounds in order of increasing electric conductance
What do you think about this answer provided to me in respect of three of these seven compounds?
The electrical conductance of a molecule depends upon its ionic or covalent nature. Ionic compounds conduct, whereas covalent compounds do not.
BeH2 is a covalent hydride. Hence, it does not conduct. 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. Hence, the increasing order of electrical conductance is as follows:
BeH2 < CaH2 < TiH2
Can we use Fajan's rules to decide the electric conductance of all of these seven compounds?

Re: Arrangement of chemical compounds in order of increasing electric conductance
I dont think so, most of them you have to melt to get conductivity.
