Sample MCQs (With Answers and Explanations):
Q1. Which of the following elements belongs to Group 13 of the periodic table?
A) Carbon B) Silicon C) Boron D) Tin
✅ Answer: C) Boron
💡 Explanation: Boron (B) is the first element of Group 13, known as the boron group, showing unique non-metallic properties.
Q2. The inert pair effect is most significant in:
A) Aluminium B) Gallium C) Thallium D) Boron
✅ Answer: C) Thallium
💡 Explanation: Thallium exhibits the +1 oxidation state due to the inert pair effect, stabilizing the 6s electrons.
Q3. Which oxide among the following is amphoteric?
A) B₂O₃ B) Al₂O₃ C) SiO₂ D) CO₂
✅ Answer: B) Al₂O₃
💡 Explanation: Aluminium oxide reacts with both acids and bases, showing amphoteric character.
Q4. Which compound demonstrates catenation most strongly?
A) SiH₄ B) SnH₄ C) C₂H₆ D) PbH₄
✅ Answer: C) C₂H₆
💡 Explanation: Carbon shows strong catenation (self-linking property) due to stable C–C bond formation.
Q5. Which element shows both +2 and +4 oxidation states due to inert pair effect?
A) Carbon B) Tin C) Silicon D) Lead
✅ Answer: B) Tin
💡 Explanation: Tin (Sn) exhibits variable oxidation states (+2, +4) due to partial participation of ns² electrons.
