Syllabus alignment

Full unit list →

Official Chemistry is broad: Physical (mole to surface), Inorganic (periodicity through coordination/qualitative), and Organic (GOC through biomolecules/polymers/practical). AdvanceReview uses three hubs; each hub below lists the official units you must finish for 2026.

  1. 1

    Physical: equilibrium + electrochemistry + kinetics are high-yield every year — schedule them weekly.

  2. 2

    Inorganic: coordination + p-block applications beat rote lists; qualitative analysis needs ion tables.

  3. 3

    Organic: GOC + mechanism logic first; then named reaction families; treat matching as independent T/F.

  4. 4

    Practical organic detection and everyday chemistry are in the syllabus — keep a short revision sheet.

Summary

  • 3 top-level topics covering 241 tagged questions.
  • Core-daily intensity topics: Physical, Organic.
  • Rising topics: Organic.
  • Falling topics: Physical.

Planning tips

  • Allocate weekly hours roughly proportional to shareOfSubject, then boost rising topics by +20%.
  • Inside each topic, drill the top 2–3 subtopics first — they usually carry >50% of that topic.
  • Use typeMix: if MC% is high, practise option-elimination; if NUM% is high, timed calculation.
  • Link weeklyPlan items to relatedMixedIds so joins are practised, not only silos.

Chemistry2026 · Paper 1 · Q8multi-correct

Multi-step organic synthesis + functional tests

Organic reaction sequence+Heterocycles+Tollens / qualitative tests

Knowledge bridge

Step 1: push each reagent in order to get intermediates Q, R, S, T. Step 2: recognise the heterocyclic closure in T. Step 3: apply Tollens (and related tests) only to the structure that still has the oxidisable group (S).

Why it feels hard

Mechanism memory plus lab-test logic in one multi-correct/sequence item.

What to practise

After every synthesis map, annotate which intermediates pass Tollens/Fehling/iodoform.

Chemistry2026 · Paper 2 · Q15–Q16linked-numerical

Ideal solution molar volumes + vapour mole fraction

Solutions – colligative / ideal+Raoult’s law+Vapour–liquid composition

Knowledge bridge

Step 1: from the linked ideal-solution data, compute the vapour-to-liquid molar volume ratio for pure B. Step 2: find liquid mole fractions (e.g. from molality). Step 3: apply Raoult to get y_B in the vapour (numerical ~0.16 style).

Why it feels hard

Two numericals share solution data; unit slips (molality vs mole fraction) are common.

What to practise

Convert every molality stem to x_i before touching vapour pressures.

Chemistry2026 · Paper 2 · Q17–Q18linked-numerical

Kjeldahl nitrogen + Carius sulphur on related organics

Organic practical – Kjeldahl+Organic practical – Carius+Stoichiometric estimation

Knowledge bridge

Step 1: from structure/formula of L, count N and convert mass to moles of NH₃, then to mL of 1 M H₂SO₄. Step 2: from M, count S and convert to grams of BaSO₄ via Carius stoichiometry. Step 3: keep atomic masses consistent across both linked estimation asks.

Why it feels hard

NCERT ‘end chapter’ methods under numerical pressure; easy arithmetic slips.

What to practise

Treat Kjeldahl/Carius as fixed stoichiometry templates — practise until automatic.
