Paper Pattern and Difficulty Analysis
The question paper was structured into three distinct sections, adhering strictly to the updated JKBOSE syllabus.
-
Section A (MCQs & Very Short Answers): Comprised 20 questions (1 mark each). The difficulty level was rated as Easy to Moderate.
-
Section B (Short Answer Questions): Focused on concept-based numericals and reaction mechanisms (3–4 marks each). This section was considered Moderate to Tricky.
-
Section C (Long Answer Questions): involved in-depth theoretical and application-based topics. While Moderate, many students found this section Lengthy.
Expert Review: “The paper was balanced and student-friendly. Concept clarity was more important than memorization, and no out-of-syllabus questions were reported.” — Senior Chemistry Lecturer
Student Reactions and Polls
Early reactions from exam centers across the Winter Zone suggest a generally positive response, though time management was a key factor.
-
36% of students found the paper Easy.
-
48% rated it as Moderate.
-
16% found it Difficult.
Common feedback included satisfaction with the Organic Chemistry section, which was scoring for those who studied reaction mechanisms well. However, Physical Chemistry numericals were cited as challenging due to the calculation steps involved.
Sample Questions from Today’s Paper
To give an idea of the conceptual depth, here are a few questions asked in the exam:
-
Define rate constant and give its SI unit.
-
Write the IUPAC name of:
CH₃ — CH₂ — CH₂ — Cl -
State Faraday’s First Law of Electrolysis.
-
Explain the mechanism of nucleophilic substitution reaction in haloalkanes.
Conclusion
The JKBOSE Class 12th Chemistry paper for the Winter Zone 2025 was largely NCERT-based and balanced. Students who focused on NCERT examples, exercises, and named reactions are expected to score well (45+ marks). Stakeholders and students should now focus on the upcoming core subjects, with Physics and Biology expected to follow soon.
