Concepts that repeat
In our data no single concept dominates Hydrocarbons. Its questions are spread across the syllabus, so work through every sub-topic rather than a short list.
What the syllabus covers
Alkanes, alkenes, alkynes and aromatic hydrocarbons: nomenclature, preparation, reactions, mechanisms of halogenation, electrophilic addition and electrophilic substitution, Friedel-Crafts reactions.
A checklist to tick off:
- Alkanes
- Alkenes
- Alkynes and aromatic hydrocarbons: nomenclature
- Preparation
- Reactions
- Mechanisms of halogenation
- Electrophilic addition and electrophilic substitution
- Friedel-Crafts reactions
What to focus on
Reaction mechanisms of alkenes and aromatics, named reactions with their products, and isomerism.
A study plan for this chapter
Treat it as a dependable source of marks and keep it in your regular revision cycle. If you divide your Chemistry time in proportion to recent weightage, this chapter earns about 6% of it.
- Week 1: one careful pass through theory and solved examples.
- Week 2: chapter-wise PYQs in two sittings. Aim for accuracy first and speed second.
- Week 3: fix every error from your log and take a timed set of 25 mixed questions.
- Ongoing: revisit once a week and again before each mock test.
