Arrange the following:
$(i)$ $CaH_2$,$BeH_2$ and $TiH_2$ in order of increasing electrical conductance.
$(ii)$ $LiH$,$NaH$ and $CsH$ in order of increasing ionic character.
$(iii)$ $H-H$,$D-D$ and $F-F$ in order of increasing bond dissociation enthalpy.
$(iv)$ $NaH$,$MgH_2$ and $H_2O$ in order of increasing reducing property.

Hydrogen has three isotopes: protium $(^{1}H)$,deuterium ($^{2}H$ or $D$),and tritium ($^{3}H$ or $T$). They have nearly same chemical properties but different physical properties. They differ in......
