Consider the following statements about the hydrides (I) Sodium hydride with water liberates oxygen gas (II) Methane, silane are examples of electron precise hydrides (III) Ammonia and water molecules are examples of electron deficient hydrides (IV)Hydrides of beryllium and magnesium are polymeric in structure The correct statements are
- A I & II only
- B III & IV only
- C II & IV only
- D I & IV only
Answer & Solution
Correct Answer
(C) II & IV only
Step-by-step Solution
Detailed explanation
Statement (I) is incorrect as the reaction between \(\mathrm{NaH}\) and \(\mathrm{H}_2 \mathrm{O}\) gives sodium hydroxide and hydrogen gas. \(\mathrm{NaH}+\mathrm{H}_2 \mathrm{O} \rightarrow \mathrm{NaOH}+\mathrm{H}_2 \uparrow\) Statement (III) is incorrect as \(\mathrm{NH}_3\)…
