Question Style in MHT CET Basic Principles of Organic Chemistry PYQs
Every question in this PDF is a single-correct MCQ. The chapter covers many sub-topics, so the questions are spread across naming, electronic effects and reactions.
| Question Style | What it Tests |
|---|---|
| IUPAC name | The IUPAC name of a given structure, such as 1-methoxy-2,2-dimethylbutane or 3-bromo-4-ethylbut-3-ene |
| Hybridisation | The hybridisation in H₂Se and the number of sp³ carbon atoms in HO(CH₂)₃CH(CH₃)CH(CH₃)₂ |
| Electronic effects | The groups that show an electron donating or withdrawing inductive effect, and matching the inductive effect, resonance and hyperconjugation with their descriptions |
| Isomerism and configuration | A pair of compounds that shows functional group isomerism, and the group of highest priority in the R, S system |
| Reactions and calculations | The product of an organic reaction, the yield of aspirin from salicylic acid and acetic anhydride, and the reaction of ethyl bromide with sodium iodide in dry acetone |
How to Use the Basic Principles of Organic Chemistry PYQ PDF for MHT CET
- Start with the 2025 and 2026 papers first, because they hold 23 of the 75 questions.
- Practise the IUPAC rules for the longest chain, the lowest locants and the order of priority of functional groups.
- For electronic effects, remember that alkyl groups show a +I effect and halogens, -NO₂ and -CN show a -I effect.
- Solve year-wise PYQs by timing yourself, as time management is crucial.
- Re-attempt only the questions you got wrong, and note which formula or step you missed.
