UP Board Chemistry: Phase 2 Roadmap (2026)
Units 4, 5 & 6 | Exam Target: Feb 18, 2026
UNIT 4: d & f BLOCK ELEMENTS 06 MARKS
Setter's Insight: Is chapter se direct "Why" wale questions aate hain. Transition elements ki properties aur Lanthanoid contraction par focus karo[cite: 21, 22].
Guaranteed 2 Marks
1. Lanthanoid Contraction:
Study: Its cause (poor shielding of 4f electrons) and consequences on atomic size.
Numerical/Reasoning
2. Magnetic Properties:
Calculate magnetic moment using spin-only formula:
$$\mu = \sqrt{n(n+2)} \text{ BM}$$
Where \(n\) = number of unpaired electrons
3. General Trends: Variable oxidation states, formation of colored ions (d-d transition), and catalytic properties.
UNIT 5: COORDINATION COMPOUNDS 07 MARKS
Setter's Insight: IUPAC naming fix hai (2 marks). Iske alawa VBT ya CFT se geometry aur hybridization puchi jayegi.
100% Asked
1. IUPAC Nomenclature:
Practice naming complex ions like \([Co(NH_3)_6]Cl_3\) or \(K_4[Fe(CN)_6]\).
2. Werner's Theory: Difference between Primary and Secondary valency.
Long Answer (3-4 Marks)
3. VBT and CFT:
Study inner/outer orbital complexes and Crystal Field Splitting in octahedral/tetrahedral fields.
UNIT 6: HALOALKANES & HALOARENES 07 MARKS
Setter's Insight: Organic start ho rahi hai. Mechanistic logic par dhyan do, especially $S_N1$ and $S_N2$[cite: 29].
Mechanism Focus
1. Nucleophilic Substitution:
Difference between \(S_N1\) (two steps, carbocation) and \(S_N2\) (single step, inversion)[cite: 29].
2. Name Reactions:
Finkelstein, Swarts, Wurtz-Fittig, and Sandmeyer reaction[cite: 29].
Application Based
3. Environmental Impact:
Uses and environmental effects of DDT, Freons, Chloroform, and Iodoform[cite: 31].
2026 TOPPER'S CHECKLIST
- Coordination compounds ki IUPAC naming ki daily 5 mins practice karein.
- d-block se oxidation states ka trend zaroor padhein.
- Organic reactions ke liye separate formula notebook banayein.
Strictly as per UP Board Official Syllabus 2025-26[cite: 6].
