Sample MCQs (with Answers and Explanations):
Q1. Which of the following is an ionic hydride?
A) CH₄ B) NaH C) BH₃ D) H₂O
Answer: B
Explanation: Sodium hydride (NaH) is an ionic hydride where hydrogen exists as H⁻ (hydride ion). It reacts vigorously with water to release H₂ gas.
Q2. Which hydride is covalent in nature and forms hydrogen bonds?
A) HCl B) H₂O C) LiH D) NaH
Answer: B
Explanation: Water (H₂O) is a covalent molecular hydride capable of forming strong hydrogen bonds, explaining its high boiling point.
Q3. The combustion of hydrogen gas produces —
A) Hydrogen chloride B) Water C) Hydrogen peroxide D) Steam only
Answer: B
Explanation: Hydrogen burns in oxygen to form water (2H₂ + O₂ → 2H₂O), an exothermic reaction releasing large amounts of energy.
Q4. Which hydride acts as a reducing agent in metallurgy?
A) H₂ B) CH₄ C) HF D) NH₃
Answer: A
Explanation: Hydrogen gas (H₂) is a strong reducing agent used to extract metals from oxides, forming water as a byproduct.
Q5. In NaH, the oxidation number of hydrogen is —
A) +1 B) 0 C) -1 D) +2
Answer: C
Explanation: In ionic hydrides like NaH, hydrogen exists as H⁻ with an oxidation number of -1, showing its reducing nature.
