Interactive Chemistry Bonding & IMF Trainer: 67-Compound OFFLINE Revision Tool

Elevate your students’ understanding of chemical bonding and intermolecular forces with this comprehensive, interactive diagnostic tool.

Designed by a specialist Chemistry educator and head of science, this standalone HTML mini-app is an all-in-one solution for retrieval practice, starters, and exit tickets. It covers the four primary types of bonding (ionic, metallic, simple covalent, and giant covalent) and—crucially—forces students to differentiate between intramolecular bonds and intermolecular forces in simple covalent substances.

Key Pedagogical Features

• 67-Substance Database: An exhaustive library covering Ionic, Metallic, Giant Covalent, and Simple Covalent structures.

• Intelligent IMF Logic: For simple covalent molecules, the app prompts for the dominant Intermolecular Force (LDF, Dipole-Dipole, or Hydrogen Bonding), directly addressing common misconceptions in bonding hierarchy.

• Randomized Retrieval: Every session is unique. Students can select 10, 20, 30, 40, or 50 questions to fit the time available in a lesson.

• Metacognitive Feedback: A built-in History and Review feature allows students to analyze their mistakes, see correct explanations, and track their progress in real-time.

• Scientific Precision: Features high-resolution chemical diagrams (.svg) for maximum clarity on interactive whiteboards or 1:1 devices.

• Perfect for the Following Curricula:

1. IB Diploma (DP): Topic 4 (Chemical Bonding and Structure).
2. A-Level / AS Level: (AQA, OCR, Edexcel, CAIE).
3. AP Chemistry: Unit 2 (Molecular and Ionic Compound Structure and Properties).
4. IGCSE / GCSE: Triple Science and Higher Tier Chemistry.
