Chemistry for the JAMB Exam — New York candidates
10% of the JAMB test plan. Atomic structure, bonding, stoichiometry, organic reactions, and industrial chemistry in JAMB Chemistry. Calibrated for New Yorker candidates.
Behind every published pass rate is a distribution of which topics caused most of the failures. This is one of those topics. Chemistry sits at roughly 10% of the Joint Admissions and Matriculation Board (UTME) content distribution — JAMB Chemistry is required for medicine, pharmacy, engineering, and science admissions. The examination tests conceptual understanding and calculations including mole calculations, stoichiometry, gas laws, and electrochemistry. Organic chemistry (functional groups, reactions, IUPAC naming) carries significant marks. Pass rates for the JAMB are published annually by the awarding body and vary by cohort and locale. For New York candidates preparing for JAMB, the calibration of study to local context matters: New York is a top-3 state for NCLEX-RN, MCAT, and GRE candidates. NY State Education Department (NYSED) handles RN licensure differently from compact states.
Common failure modes
These are the patterns that cause most candidates to lose marks on this topic. Recognising them in advance is half the work.
- !Confusing the IUPAC names of organic functional groups — especially carboxylic acids vs esters
- !Mole calculation errors — forgetting to divide by molar mass when converting grams to moles
- !Misidentifying oxidation and reduction in redox reactions
Study tips
- 1Memorize molar masses of the first 20 elements and common compounds (H₂O, CO₂, HCl, NaOH, H₂SO₄).
- 2Practice the three-step mole calculation: (1) write balanced equation, (2) find mole ratios, (3) convert units.
- 3Learn to identify functional groups from structural formulas: -OH (alcohol), -COOH (acid), -COO- (ester), -NH₂ (amine), -CHO (aldehyde).
- 4For NCLEX-RN: NYSED is not part of the Nurse Licensure Compact, so a NY licence does not transfer to other states without endorsement. Consider this if you plan to work in NJ/CT after graduating.
- 5For MCAT: most NY medical schools (Columbia, Cornell, Mount Sinai, NYU) cap MCAT scores accepted at 3 years old — verify your target schools' exact policy.
- 6For CDL: NY DMV requires a 14-day permit-holding period before scheduling the CDL skills test; budget this gap into your training schedule.
Sample JAMB Chemistry questions

How many moles of oxygen are needed to completely combust 2 moles of ethane (C₂H₆)?
- A3
- B5
- C7Correct
- D14
Why this answer?
Balanced equation: 2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O. The mole ratio C₂H₆ : O₂ = 2 : 7. For 2 moles of ethane, 7 moles of O₂ are required.
