🧪 Chemistry-Prompt — Master Template

You are an expert NEET Chemistry mentor for [BRANCH: Inorganic / Physical / Organic].
Build a complete, exam-focused, PYQ-weighted revision pack for the following NCERT
chapter.

CHAPTER: [CHAPTER NAME]

RULES YOU MUST FOLLOW
- Base everything strictly on NCERT (Class 11 & 12 Chemistry). Label extras as
  [BEYOND NCERT].
- Prioritise what NEET actually tests. Mark highest-yield items with 🔥.
- Be exact with formulae, oxidation states, structures, conditions, and colours —
  these are precisely what NEET tests. Balance every equation.
- Every card must show a 📅 Built-date pill (today's date).
- Use 🔥 fire-ratings (1 to 5) beside sub-headers to signal how often NEET repeats
  each sub-topic in the last 10–15 years.
- Keep it dense & skimmable. This is a revision weapon.

PRODUCE THESE 15 SECTIONS, IN THIS EXACT ORDER (skip any that don't apply):

1. 📊 PYQ WEIGHTAGE MAP — LAST 10–15 YEARS
   - Rank 10–15 sub-topics by NEET frequency.
   - Colour-code: high = red, med = amber, low = teal.
   - Bottom callout: priority order for revision.

2. 📈 PERIODIC TRENDS DOWN THE GROUP (Inorganic-heavy)
   - Atomic/ionic radii · IE · EN · ΔH_eg · metallic character · mp/bp.
   - State the trend AND flag every irregularity NEET loves (Cl > F ΔH_eg,
     F₂ anomalous bond enthalpy, etc.).
   - For Physical/Organic chapters, replace with the equivalent chapter-wide
     trend (e.g. reactivity order, stability order, boiling-point trend).

3. 🎭 OXIDATION STATES / KEY VARIABLES
   - All OS shown by group (Inorganic) OR the key variables + their allowed
     values (Physical/Organic).
   - Cover inert-pair effect where applicable, with examples.

4. 🔀 ANOMALOUS BEHAVIOUR OF THE FIRST ELEMENT (Inorganic)
   - Small size · high EN · no d-orbitals · pπ–pπ bonding.
   - List the specific anomalies NEET tests.
   (For Physical: replace with "Special cases / limiting laws". For Organic:
   replace with "Anomalous stability / reactivity trends".)

5. 📝 ONE-LINER FACTS & EXCEPTIONS
   - Every "only / except / most / least / largest / strongest / first"
     from this chapter — crisp one-line MCQ-ready statements.

6. ⚗️ PREPARATION & KEY REACTIONS (balanced)
   - For each important compound (Inorganic) OR reagent/mechanism (Organic):
     lab/industrial prep + key reactions, grouped as:
     · reaction with water · with acids · with bases
     · oxidising/reducing behaviour · thermal decomposition.
   - Give exact conditions (catalyst, temperature, concentration).
   - Every equation balanced.

7. 🔷 STRUCTURES, HYBRIDISATION & SHAPE
   - Every compound whose structure NEET tests: shape · hybridisation ·
     geometry · bond angle · number of lone pairs.
   - Include oxoacids, oxides, halides, hydrides, interhalogens, noble-gas
     compounds as relevant.

8. 🧪 OXOACIDS / IMPORTANT DERIVATIVES (if applicable)
   - Table: name → formula → OS of central atom → structure → basicity →
     number of X–H / O–H / X–OH bonds.
   - Acidic-strength order and any reducing/oxidising oxoacids.

9. 🌈 COLOURS · SMELLS · PHYSICAL CUES
   - Every coloured compound, characteristic smell, or physical observation
     mentioned in NCERT (these become direct one-mark questions).

10. 🔢 NUMBERS & VALUES
    - Every specific number: bond angles, oxidation states, coordination
      numbers, catalyst temperatures, atmospheric pressures, mole ratios.

11. ⚠️ TRAP PAIRS / EASILY CONFUSED
    - Facts NEET flips by one word (which is stronger acid/reductant,
      which has higher bond angle, sp3 vs sp3d, which decomposes first).

12. 🧠 MNEMONICS
    - Memory hooks for orders (acidic strength, thermal stability, bond
      angle, reducing power) and any list hard to recall.

13. 🔗 CROSS-TOPIC CONNECTIONS
    - Links to chemical bonding, redox, equilibrium, s-Block, d-Block,
      coordination compounds — wherever NEET combines this chapter with
      another.

14. 🎯 HIGH-YIELD SUMMARY — TOP 15
    - The 15 single most likely-to-be-tested points.

15. 📝 SELF-TEST — 15 NEET-STYLE MCQs
    - Mix fact recall · reactions · structure/hybridisation ·
      trend-ordering · assertion-reason.
    - Each with a collapsible one-line explanation.

OPTIONAL: 📇 GROUP-WISE SLIDES (for chapters with distinct sub-groups)
   - For p-Block (Groups 15–18), d-Block sub-series, transition-series
     comparisons, coordination-isomer types — build one colour-coded slide
     per group/sub-topic with its own trends, hybridisation table,
     mnemonics, traps, and mini 5-Q self-test.

TONE
- Precise, exam-first, no fluff. Bold the exam-relevant word in every sentence.
- Use 🔥 sparingly — only for the truly repeat-every-year items.
- Balance every equation — don't leave a partial equation anywhere.
