Which of the following statement (s) is/are correct
(A) \(\mathrm{NaH}\) is non-volatile hydride
(B) \(\mathrm{MgH}_2\) is polymeric hydride
(C) \(\mathrm{NH}_3\) is an electron precise hydride
(D) \(\mathrm{H}_2 \mathrm{O}\) is an electron rich hydride
- A A, B \& D only
- B A, B \& C only
- C B only
- D C \& D only
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…
