Introduction Paragraph
Hydrogen and Its Compounds form the foundation of Inorganic Chemistry in Chapter 9: Hydrogen of the CBSE Class 11 Chemistry syllabus. This topic deals with the types of hydrides — ionic, covalent, and interstitial — as well as the unique properties and reactions of hydrogen-containing compounds such as water, hydrogen peroxide, and metal hydrides. Understanding these compounds is essential for grasping concepts related to oxidation-reduction reactions, acid-base behavior, and hydrogen bonding, which are frequently tested in board exams and competitive exams.
This CBSE Class 11 Chemistry MCQ Online Practice Test follows the latest NCERT guidelines, providing a well-structured set of multiple-choice questions designed for deep conceptual understanding. Each question includes instant scoring and feedback, helping students identify their weak areas and improve accuracy.
Ideal for CBSE Board Exams, JEE, and NEET, this quiz enhances problem-solving ability through interactive learning and precise conceptual coverage of hydrogen and its compounds.
Sample MCQs (with Answers and Explanations):
Q1. Which hydride is a covalent compound?
A) NaH B) CaH₂ C) CH₄ D) LiH
Answer: C
Explanation: Methane (CH₄) is a covalent (molecular) hydride formed by carbon and hydrogen through electron sharing.
Q2. Which compound exhibits hydrogen bonding?
A) CH₄ B) H₂S C) H₂O D) HCl
Answer: C
Explanation: In water (H₂O), hydrogen atoms form intermolecular hydrogen bonds with oxygen, resulting in its high boiling point.

A) H₂O B) HCl C) NaH D) H₂
Answer: C
Explanation: In sodium hydride (NaH), hydrogen exists as H⁻ (hydride ion) with an oxidation state of -1.
Q4. Which of the following is an interstitial hydride?
A) PdHₓ B) CH₄ C) NaH D) H₂O₂
Answer: A
Explanation: Palladium hydride (PdHₓ) is an interstitial hydride where hydrogen occupies voids in the metal lattice.
Q5. Which compound acts as an oxidizing agent among hydrogen compounds?
A) CH₄ B) H₂O C) H₂O₂ D) NH₃
Answer: C
Explanation: Hydrogen peroxide (H₂O₂) acts as both an oxidizing and reducing agent, depending on the reaction conditions.
