This comprehensive guide breaks down the essential strategies, study frameworks, and exam techniques that top-performing students use to crack the Edexcel IAL Chemistry exam and secure an A* grade.
Crude oil is separated by fractional distillation into fractions (e.g., naphtha, kerosene, diesel). There is a greater demand for short-chain molecules (petrol, alkenes for plastics) than is supplied by primary distillation. Cracking is the process of breaking strong C–C and C–H bonds in long-chain alkanes. Cracking is the process of breaking strong C–C
– Focuses on atomic structure, formulas, equations, energetic trends, and basic alkanes/alkenes. This likely refers to students who have excelled
