What this set is
This is an original Doubtly set of 24 most important questions for the Mumbai University FE Semester 1 Applied Chemistry (BSC103, NEP 2020 scheme) exam in Winter 2026. It is not an official university paper and does not predict the actual paper. Questions are grouped module by module, four per module, and every question has a full model answer written by Doubtly. Marks (3, 4, 5 or 6) follow the way such questions are marked in recent MU papers.
How the questions were chosen
We went through the last three Applied Chemistry papers (December 2024, June 2025 KT and December 2025) and listed the question type behind every sub-question. Types that came in two or three of these papers were picked. Some questions are taken as-is from those papers, and their stems say which paper they came from; the rest are new questions of the same type, with new numbers for the numericals.
| Module and question type | Dec 2024 | June 2025 KT | Dec 2025 |
|---|---|---|---|
| Fuels: gross and net calorific value by Dulong's formula | Yes | Yes | Yes |
| Fuels: ultimate analysis, % sulphur and % nitrogen (Kjeldahl) | Yes | Yes | Yes |
| Corrosion: factors affecting the rate of corrosion | Yes | Yes | No |
| Corrosion: cathodic protection, material selection and design | Yes | Yes | Yes |
| Alloys: phase rule terms, reduced phase rule, Pb–Ag diagram | Yes | Yes | Yes |
| Alloys: mass of eutectic numerical | Yes | Yes | Yes |
| Polymers: number and weight average molecular weight numerical | Yes | Yes | No |
| Polymers: properties (Tg, tensile strength, electrical, optical) | Yes | Yes | Yes |
| Composites: matrix and dispersed phase | Yes | Yes | Yes |
| Composites: laminar/sandwich, fibre-reinforced composites | Yes | Yes | No |
| Green chemistry: adipic acid by traditional and green routes | No | Yes | Yes |
| Green chemistry: biodiesel | No | Yes | Yes |
| Green chemistry: supercritical CO₂ / green solvents | Yes | Yes | Yes |
The calorific value numerical and the mass-of-eutectic numerical came in every paper, and the Cd–Bi eutectic problem appeared with the same numbers in both 2025 papers (it is included as-is, Q.12), so practise the method until it is automatic. The synthesis of indigo by the green route, the principles of green chemistry, and crystallinity and fatigue of polymers each came once; revise them from your notes as well.
How to use this set
Try each question on paper first, under time: about 2 minutes per mark, the pace of the real 45-mark, 90-minute exam. For theory answers, write points with a heading for each and draw the diagram described in the solution; for numericals, write the formula, the substitution and the unit. Every numerical answer here was checked with Python.
FAQs
Are these the questions that will come in the Winter 2026 exam?
No one can promise that. These are the question types that repeated most across the last three papers, so they are the best use of revision time, but study the full syllabus too.
Why are some questions marked "asked in MU"?
Those questions were set by the university in the paper named, so you can see the exact exam wording. All other questions are new ones of the same type, and all answers are Doubtly's own.
What is the actual exam pattern?
The recent papers are 45 marks in 1 hour 30 minutes. Q.1 has seven 3-mark questions (attempt any five, 15 marks). Q.2 to Q.5 each have three parts worth 6, 5 and 4 marks, and you attempt any two of these four questions (30 marks).
