Sample MCQs (With Answers and Explanations):

Q1. Which element is the first member of the Boron Family?
A) Aluminium B) Boron C) Gallium D) Indium
✅ Answer: B) Boron
💡 Explanation: Boron (B) is the first element of Group 13, showing non-metallic properties and forming covalent compounds like B₂H₆.

Q2. Which Group 14 element shows the strongest catenation property?
A) Silicon B) Carbon C) Germanium D) Tin
✅ Answer: B) Carbon
💡 Explanation: Carbon exhibits maximum catenation due to strong C–C bond strength and small atomic size.

Q3. Which oxide of aluminium is amphoteric in nature?
A) Al₂O₃ B) B₂O₃ C) CO₂ D) SiO₂
✅ Answer: A) Al₂O₃
💡 Explanation: Aluminium oxide reacts with both acids and bases, showing amphoteric character typical of metalloid behavior.

Q4. Which compound exhibits a three-center two-electron bond?
A) CH₄ B) SiH₄ C) B₂H₆ D) CO₂
✅ Answer: C) B₂H₆
💡 Explanation: Diborane (B₂H₆) has bridging hydrogen atoms linked by 3-center-2-electron bonds due to boron’s electron deficiency.

Q5. Which element forms the stable dioxide used in glass manufacturing?
A) Carbon B) Silicon C) Germanium D) Lead
✅ Answer: B) Silicon
💡 Explanation: Silicon dioxide (SiO₂) is the primary component of glass and ceramics, forming a strong network covalent structure.
