  4. D C \& D only
Verified Solution

Answer & Solution

Correct Answer

(A) A, B \& D only

Step-by-step Solution

Detailed explanation

\(\mathrm{NH}_3\) is an electron-rich hydride as \(\mathrm{N}\)-atom has a lone pair on it. Thus, (C) is incorrect. \(\mathrm{NaH}\) being an ionic hydride is non-volatile. Thus, (A) is correct. \(\mathrm{MgH}_2\) is a polymeric hydride due to bridging hydrogens. Thus, (B) is…
