About the BSEB Intermediate Chemistry Exam
BSEB Intermediate Chemistry covers Class 12 (I.Sc. elective) chemistry under the Bihar School Examination Board, subject code 118. Content prioritises NCERT Class 12 Chemistry: Solutions, Electrochemistry, Chemical Kinetics, d- and f-Block Elements, Coordination Compounds, Haloalkanes and Haloarenes, Alcohols Phenols and Ethers, Aldehydes Ketones and Carboxylic Acids, Amines, Biomolecules, Polymers, Chemistry in Everyday Life, and solid-state/surface topics if retained in the notified syllabus for the year. Official assessment is written theory (~70 marks, ~3 h 15 min) plus practical (~30 marks), not multiple choice alone. This free English MCQ bank builds concept and calculation fluency before students practise official model papers and practical skills using resources from biharboardonline.com and NCERT.
Exam sponsor: Bihar School Examination Board (BSEB). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.
Assessment
Official BSEB Intermediate Chemistry assesses Class 12 content through a theory paper of about 70 marks lasting about 3 hours 15 minutes (subject code 118), typically with objective-type questions plus short and long answer sections, and a practical / internal assessment of about 30 marks conducted separately. Confirm the current model paper and notification for section weights and internal choice. This 100-question bank is an English-language MCQ study adaptation of that written syllabus — it does not fully simulate the official multi-section paper or lab practical format.
Time Limit
Typically 3 hours 15 minutes for the official Intermediate Chemistry theory paper (subject code 118), as printed on BSEB Intermediate model and annual papers. Practical exams are scheduled separately.
Passing Score
About 30% of maximum marks is the usual BSEB Intermediate pass benchmark range; Chemistry candidates must satisfy separate theory and practical pass rules as notified. Some secondary summaries quote about 33/100 aggregate — confirm the current year circular rather than unofficial fixed numbers.
Exam / Certification Fees
Included in the Intermediate examination fee schedule notified annually by BSEB. Exact rupee amounts vary by year and candidate category; check the latest fee notification on biharboardonline.com rather than unofficial fixed quotes.
Exam sponsor websiteFees, eligibility, and exam policies can change. Confirm them with the exam sponsor before applying or paying.
Our practice resources: topics covered
We aim to reflect publicly available exam outlines and topic information in our study resources. Coverage, format, and difficulty may differ from the actual exam, and we cannot guarantee that every detail is accurate or current. Confirm exam requirements, fees, and policies with the official exam sponsor.
Solutions & Colligative Properties
Molarity/molality/mole fraction, Raoult's law, elevation/depression formulas, and osmotic pressure / van't Hoff factor.
Electrochemistry
Cell notation, E°cell, Nernst basics, Kohlrausch ideas, and Faraday electrolysis calculations.
Chemical Kinetics
Rate expressions, order determination, first-order half-life, and temperature dependence of rate.
d/f-Block & Coordination Chemistry
Transition-metal properties, lanthanoid contraction, ligands, IUPAC names, isomerism, and CFT colour/magnetism basics.
Organic Chemistry
Halo compounds through amines: mechanisms, named reactions, and distinguishing chemical tests.
Biomolecules, Polymers & Everyday Chemistry
Sugars, amino acids/proteins, nucleic acids; addition/condensation polymers; common drugs and cleansing agents.
Solid/Surface & Cross-topic Calculations
Unit cells and adsorption/colloid ideas if in syllabus; multi-step numerical practice across physical chemistry.

Frequently Asked Questions
Is the official BSEB Intermediate Chemistry exam only multiple choice?
No. Official Intermediate Chemistry theory papers (subject code 118) mix objective-type items with short and long constructed-response questions over about 3 hours 15 minutes, plus a practical component of about 30 marks. This bank is an English-language MCQ study adaptation for concept and calculation practice only — not a complete official-format simulation.
Does Intermediate Chemistry include a practical exam?
Yes. Chemistry is a practical-bearing science subject under BSEB. Theory is typically about 70 marks and practical / internal assessment about 30 marks. Candidates must complete prescribed practical work and appear as scheduled.
How long is the Chemistry theory paper and how many marks is it?
Theory duration is typically 3 hours 15 minutes for about 70 marks (subject code 118), with practical about 30 marks separate. Confirm the model paper and notification for your sitting on biharboardonline.com.
What is the passing score for Intermediate Chemistry?
BSEB Intermediate pass rules are generally near about 30% of maximum marks, with separate theory and practical requirements for practical-bearing subjects. Some guides quote about 33/100 aggregate. Always confirm the current year circular.
What does Intermediate Chemistry cost to take?
Chemistry is examined as part of the Intermediate examination. Fees are set annually by BSEB in official fee notifications and are not a single fixed public "chemistry-only" price. Check biharboardonline.com for the current schedule.
Which topics should I prioritise?
Cover NCERT Class 12 Chemistry as retained by BSEB: Solutions, Electrochemistry, Chemical Kinetics, d/f-block, Coordination Compounds, and organic chapters from haloalkanes through biomolecules (plus polymers/everyday chemistry and solid/surface if notified). Drill molarity, kinetics order/half-life, and cell EMF calculations. Use official model papers (code 118) alongside this MCQ bank.
