Inorganic Chemistry Exceptions for JEE Main

Test your knowledge of inorganic chemistry exceptions for JEE Main — the anomalies that break expected periodic trends and show up again and again in the exam.

Twenty-five questions in five sections: the lithium anomaly, back bonding and Group 13, the octet and covalency, the halogens and the inert pair effect, and the d-block with the lanthanide contraction.

Built around exactly the exceptions JEE examiners ask about — not generic periodic table trivia.

What This Quiz Covers

  • Lithium's anomalous behavior and the Li–Mg diagonal relationship
  • Back bonding: why BF₃ is a weaker Lewis acid than BCl₃
  • Gallium's ionization enthalpy and boron's melting point
  • Why nitrogen forms no NCl₅ and oxygen no OF₆
  • Electron affinity of chlorine vs. fluorine, and why HF is weak
  • The inert pair effect down Groups 13–16
  • Anomalous configurations of chromium and copper
  • The lanthanide contraction and the zirconium–hafnium pair
