NEB Class 12 Chemistry study guide
NEB Class 12 Chemistry · Work through your exam, one topic at a time.
NEB Class 12 Chemistry (कक्षा १२ रसायन विज्ञान) is the chemistry paper within the Grade 12 examinations conducted by the National Examinations Board (NEB), Sanothimi, Bhaktapur, under the Government of Nepal. It is taken by Grade 12 science-stream students who need the subject for their School Leaving Certificate profile and for university admission in science, health, engineering and related fields. The board publishes a Grade 12 Assessment Framework and downloadable sample question papers (नमुना प्रश्नपत्रहरू), and it publishes separate annual and supplementary (मौका/पूरक) examination timetables. The official notice list shows Chemistry treated as a full subject for result processing: there are published re-totaling result notices for Grade 12 Chemistry specifically, and Chemistry appears alongside Physics, Biology and Computer Science in a combined re-totaling notice. The NEB Class 12 Chemistry study guide has 4 sections and about 1,241 words.
01General and Physical Chemistry
This domain tests the quantitative core of the NEB Class 12 course: volumetric analysis, ionic equilibrium, chemical kinetics, thermodynamics and electrochemistry. Expect numericals that combine a formula with a unit check, plus short conceptual questions on why a reaction is spontaneous or why an indicator changes colour.
322 words, about 2 min02Inorganic Chemistry
The inorganic section of NEB Class 12 focuses on transition metals, coordination compounds, heavy metals and periodic trends. Questions ask you to write configurations, assign oxidation states, name complexes and explain colour or magnetism using crystal-field ideas.
309 words, about 2 min03Organic Chemistry
Organic chemistry in NEB Class 12 covers haloalkanes and haloarenes, alcohols, phenols, ethers, aldehydes, ketones, carboxylic acids and amines. The exam rewards correct IUPAC names, reagent-based distinctions and mechanism arrows with the right intermediates.
289 words, about 1 min04Analytical and Applied Chemistry
This domain connects laboratory measurement with real materials: volumetric and gravimetric analysis, instrumental methods, polymers, dyes, drugs, fertilisers, soaps and detergents. NEB questions often use a short calculation followed by an applied-reasoning part.
