CBSE Class 12 Chemistry - Sample Paper Blueprint & Marking Schemes Review theory/practical weightage, model papers, organic reaction mechanisms, and step-wise mark allocations. 📋 CBSE Class 12 Chemistry Exam Pattern & Marks Distribution:
• Total Marks: 100 (Theory: 70 + Practical: 30).
• Time Allowed: 3 Hours (Theory). • Question Paper Structure: Draws from Physical Chemistry, Inorganic Chemistry, and Organic Chemistry. • Question Mix: Around 50% competency-based questions (MCQs, assertion-reasoning, case/source-based), the rest short and long answer, mostly with internal choices. • Practical (30 Marks): Volumetric/qualitative analysis experiments, salt analysis, project, and viva voce. Sample 1-Mark Question (MCQ): The coordination number of Ni in the complex [Ni(NH₃)₆]²⁺ is:
Step-wise Marking Scheme:
• Correct Answer (1 Mark): 6. • Reasoning: Each of the six NH₃ ligands donates one lone pair to the central Ni²⁺ ion, giving an octahedral geometry with coordination number 6. Sample 5-Mark Question (Long Answer): (a) Write the IUPAC name and structure of the product formed when phenol reacts with bromine water. (b) Explain why phenol undergoes electrophilic substitution more readily than benzene.
Marking Allocation:
1. Product/Structure: 2,4,6-Tribromophenol, with correct structure (2 Marks). 2. Reasoning - Resonance: The -OH group donates electron density into the ring through resonance, increasing electron density at ortho/para positions (2 Marks). 3. Reasoning - Rate: This activates the ring towards electrophilic attack, so bromination occurs without a catalyst, unlike benzene (1 Mark). 📌 Evaluation Criteria followed by Board Examiners in Chemistry:
• Correct IUPAC Nomenclature: Structures and names must follow IUPAC conventions precisely for full marks.
• Mechanism Steps: Reaction mechanism questions are marked step-wise (formation of intermediate, arrow-pushing, final product). • Balanced Equations: Numerical and electrochemistry questions require balanced equations with correct units. |
