Vedclass · Answer

(B) The ionic character of metal hydrides depends on the electronegativity difference between the metal and hydrogen. As we move down the group from $Li$ to $Cs$,the electronegativity of the alkali metal decreases. Consequently,the electronegativity difference between the metal and hydrogen increases,leading to an increase in the ionic character of the metal hydride. Therefore,the order of increasing ionic character is $LiH Hence,the correct option is $B$.

The correct order of increasing ionic character among $LiH$,$NaH$,$KH$,$RbH$,$CsH$ is
