📚 Introduction
CBSE Class 11 Chemistry MCQs – VSEPR Theory and Hybridization are designed to help students master molecular geometry and bonding concepts as per the NCERT Class 11 Chemistry syllabus. This topic from Chapter 4: Chemical Bonding and Molecular Structure introduces how the shape of a molecule is determined by Valence Shell Electron Pair Repulsion (VSEPR) theory and the concept of hybridization of orbitals.
These NCERT-based online practice MCQs focus on predicting molecular shapes, bond angles, and types of hybridization (sp, sp², sp³, sp³d, sp³d²) with examples like BF₃, NH₃, SF₄, XeF₂, and IF₅. Designed strictly for CBSE Class 11 students, these questions provide conceptual clarity for board exams and competitive exams such as JEE Main and NEET.
Each question includes detailed feedback and explanations to help students understand not just the correct answer but also the logic behind molecular geometry. Attempt this 30-minute timed quiz to test your understanding of VSEPR theory and hybridization — a fundamental topic for mastering chemical bonding.
🧩 Sample MCQs (with Answers and Explanations):
Q1. VSEPR theory helps in predicting:
a) Melting point of solids b) Shape of molecules c) Atomic mass d) Rate of reaction
✅ Answer: b) Shape of molecules
Explanation: VSEPR theory explains molecular shapes by minimizing repulsion between electron pairs in the valence shell of the central atom.
Q2. What is the hybridization of carbon in CH₄?
a) sp b) sp² c) sp³ d) sp³d
✅ Answer: c) sp³
Explanation: Carbon in methane (CH₄) forms four sigma bonds using sp³ hybrid orbitals, resulting in a tetrahedral shape.
Q3. Which of the following has trigonal planar geometry?
a) NH₃ b) BF₃ c) H₂O d) CH₄
✅ Answer: b) BF₃
Explanation: In BF₃, boron is sp² hybridized, and the molecule has a trigonal planar geometry with 120° bond angles.
Q4. The hybridization of sulfur in SF₆ is:
a) sp³ b) sp³d c) sp³d² d) d²sp³
✅ Answer: c) sp³d²
Explanation: Sulfur in SF₆ uses one s, three p, and two d orbitals to form six equivalent sp³d² hybrid orbitals with octahedral geometry.
Q5. Which molecule has a T-shaped structure according to VSEPR theory?
a) ClF₃ b) BF₃ c) SF₆ d) PCl₅
✅ Answer: a) ClF₃
Explanation: ClF₃ has five electron pairs (three bonding and two lone pairs), giving a T-shaped molecular geometry.
✅ Highlight: These MCQs are strictly based on NCERT Class 11 Chemistry and ideal for CBSE board exam preparation, providing clear explanations and in-depth concept practice for students.
