CBSE Class 11 Chemical Bonding MCQs – Ionic and Covalent Bond Practice Test
📚 Introduction
CBSE Class 11 Chemistry MCQs – Ionic, Covalent, and Coordinate Bonds are designed according to the NCERT Class 11 Chemistry syllabus under Chapter 4: Chemical Bonding and Molecular Structure. This topic forms the foundation of physical and inorganic chemistry, helping students understand how atoms interact to form molecules and compounds.
These NCERT-based practice questions focus on the formation and characteristics of ionic, covalent, and coordinate bonds, including topics like electronegativity difference, bond polarity, bond energy, and Fajans’ rules. Each MCQ is paired with detailed explanations to reinforce understanding and enhance exam preparation for CBSE board exams, school tests, and competitive exams like JEE Main and NEET.
Students can test their conceptual clarity with this 30-question interactive quiz that features automatic scoring, instant feedback, and a timer — perfect for self-assessment and board-level preparation. Strengthen your chemistry basics and master bond formation and properties through this well-structured online practice test.
🧩 Sample MCQs (with Answers and Explanations):
Q1. Which bond is formed by the complete transfer of electrons from one atom to another?
a) Covalent bond b) Ionic bond c) Metallic bond d) Coordinate bond
✅ Answer: b) Ionic bond
Explanation: Ionic bonds form when one atom donates electrons to another, resulting in oppositely charged ions held by electrostatic forces.
Q2. Which molecule contains both covalent and coordinate bonds?
a) H₂O b) NH₄⁺ c) CH₄ d) CO₂
✅ Answer: b) NH₄⁺
Explanation: In ammonium ion (NH₄⁺), three N–H bonds are covalent, while one N→H⁺ bond is coordinate.
Q3. The bond in which both electrons come from the same atom is called:
a) Ionic b) Coordinate c) Metallic d) Polar covalent
✅ Answer: b) Coordinate
Explanation: In a coordinate (dative) bond, one atom donates both electrons to the shared pair, such as in H₃O⁺ or NH₄⁺.
Q4. Which compound shows maximum ionic character?
a) H–Cl b) Na–Cl c) C–H d) O–H
✅ Answer: b) Na–Cl
Explanation: Sodium chloride exhibits maximum ionic character due to a large electronegativity difference between Na and Cl.
Q5. According to Fajans’ rules, covalent character in ionic compounds increases when:
a) The cation is large and has low charge
b) The cation is small and highly charged
c) The anion is small and less polarizable
d) The electronegativity difference is high
✅ Answer: b) The cation is small and highly charged
Explanation: A small, highly charged cation distorts the anion’s electron cloud, increasing covalent character in an ionic bond.
✅ Highlight: These MCQs are based on NCERT Class 11 Chemistry concepts and are perfect for CBSE board exam and competitive exam preparation, helping students strengthen their understanding of chemical bonding fundamentals.
