Vedclass · Accepted Answer

$NH_3$ and $B_2H_6$

Vedclass · Answer

(A) $NaH$ and $CaH_2$ are ionic (saline) hydrides because they are formed by the transfer of electrons from electropositive metals to hydrogen. $NH_3$ and $B_2H_6$ are covalent (molecular) hydrides because they are formed by the sharing of electrons between non-metals and hydrogen. Therefore,the correct option is $A$.

Among $CaH_2$,$NH_3$,$NaH$,and $B_2H_6$,which are covalent hydrides?
