This topic, from Chapter 4: Physical Chemistry, helps students understand the nature of chemical bonds, molecular geometry, hybridisation, VSEPR theory, and molecular orbital theory.
These NCERT-based online practice questions enable students to test their knowledge of key ideas such as bond formation, bond order, polarity, bond length, energy relationships, resonance, and electron distribution. Each question is designed to match the CBSE Class 11 board exam standard and provides immediate feedback for self-evaluation.
This interactive MCQ quiz is ideal for students preparing for CBSE exams and competitive tests like JEE and NEET, ensuring strong conceptual grounding in one of chemistry’s most important chapters — Chemical Bonding and Molecular Structure. Attempt this online test to master both theory and application effortlessly.
🧩 Sample MCQs (with Answers and Explanations):
Q1. The VSEPR theory helps to:
a) Predict molecular shapes b) Explain ionization energy c) Determine atomic size d) Calculate electronegativity
✅ Answer: a) Predict molecular shapes
Explanation: VSEPR (Valence Shell Electron Pair Repulsion) theory predicts molecular shapes based on repulsion between electron pairs around the central atom.
Q2. Which hybridisation is found in methane (CH₄)?
a) sp b) sp² c) sp³ d) sp³d
✅ Answer: c) sp³
Explanation: In methane, one s and three p orbitals hybridize to form four equivalent sp³ orbitals giving a tetrahedral shape.
Q3. Which molecule shows hydrogen bonding?
a) CH₄ b) NH₃ c) Cl₂ d) CO₂
✅ Answer: b) NH₃
Explanation: Hydrogen bonding occurs when hydrogen is bonded to a highly electronegative atom like nitrogen, oxygen, or fluorine.
Q4. Which of the following is a property of ionic compounds?
a) Low melting point b) Conduct electricity in molten state c) Covalent bonding d) Non-conductive in molten form
✅ Answer: b) Conduct electricity in molten state
Explanation: Ionic compounds conduct electricity when molten or dissolved in water due to the movement of free ions.
Q5. The bond order of O₂ molecule is:
a) 1 b) 1.5 c) 2 d) 3
✅ Answer: c) 2
Explanation: From molecular orbital theory, O₂ has 16 electrons, and bond order = (8 bonding – 4 antibonding)/2 = 2.
✅ Highlight: These MCQs are strictly NCERT-aligned, ideal for CBSE Class 11 Chemistry revision and competitive exam preparation, offering a mix of concept-based and application-level practice.
