Edexcel A Level Chemistry: Exam Questions

This flashcard set provides explanations for molecular shapes and trends in chemical behavior. It covers the geometry of phosphorus (III) chloride due to electron pair repulsion, the thermal stability of nitrates based on cation size and charge, and the increase in boiling points from chlorine to iodine due to stronger London dispersion forces.
