The Maharashtra Board Class 12 Chemistry Previous Year Question Papers with Solutions for the last three years are very useful for students studying for their final class 12 Maharashtra board exam. These papers clearly depict the pattern of questions and their distribution, pour out the scheme of marks, and definitely give an idea about how to distribute time during the exam among all parts. By continuously practicing these papers, one would be able to get the feel of the exam, know the important topics, and perceive the stress being mapped onto various segments of the syllabus.
Here, with these question papers, come their solutions tailored meticulously by subject experts so that students get an exact and elaborative explanation. This helps in the simplification of complex concepts and thereby enhances understanding and strengthens learning processes.
This also helps in the development of their time management skills, due to which they spend their time effectively in completing the exam within the given time frame.
Analysis of the Maharashtra State Board class 12 Chemistry previous year question papers brings out certain significant trends that can guide students in their preparation. During the last few years, the question papers have maintained a balanced mix of theoretical problems and numerical problems, pointing toward the comprehensiveness of the prescribed syllabus. Some key trends that were spotted are as follows:
Year 2024: The very recent paper in 2024 comprises a balanced mixture of topics; however, questions on solid state, chemical kinetics, and polymers have been predominantly featured. Some of the practical-based and experiment-based questions were on trends of modernity towards application-based learning. That is the way of times in education and one of the major moves by the Maharashtra board towards application-based learning.
Year 2023: The 2023 paper had slightly different questions but still maintained a heavy focus on Organic Chemistry and Solutions. Some specific areas that were significantly assessed include reaction mechanisms, alcohols, phenols, ethers, and types of solutions. This could be due to the emerging trend to adapt the examination content according to entrance examinations to various fields, including Medical and Pharmaceutical studies. This means an emphasis on some foundational concepts that are very fundamental in higher studies within these fields.
Year 2022: The paper in 2022 was majorly focused on Physical Chemistry, with emphasis on thermodynamics, chemical kinetics, and chemical equilibrium. Many questions were numerically based, especially those on reaction rates, activation energy, and the equilibrium constant, another hallmark of applications of chemistry as against its mere comprehending phase. This emphasis is part of a more universal trend in education toward problem-solving and analytical skills.
Q1. Explain Wolf-Kishner reduction reaction.
Solution: The Wolf-Kishner reduction is a reaction that reduces the carbonyl group of aldehydes and ketones to a methylene group on treatment with zinc-amalgam and hydrazine followed by heating with sodium or potassium hydroxide in high boiling solvent like ethylene glycol (Wolf-Kishner reduction).
Wolf-Kishner reduction is used to synthesize straight chain alkyl substituted benzenes which is not possible by FriedelCrafts alkylation reaction.
Q2. Write postulates of Werner's theory of coordination complexes.
Solution: The postulates of Werner's theory are as follows:
Q3. Convert the cumene to phenol.
Solution: Cumene when undergoes oxidation in the presence of Oxygen followed by a reaction with conc. sulphuric acid forms phenol as a product.
Q 4. Explain the anomalous behaviour of oxygen in group 16 with respect to:
Solution: Anomalous behaviour of oxygen:

While preparing for the Class 12 Chemistry examination, remember that regular practice and consistency are your best friends. PYQs will give you the significant edge you need in filtering important topics and making you aware of what types of questions to anticipate. Use summary notes, flashcards, and regular revision to stamp the concepts in your mind. Also, do not hesitate to ask for help whenever needed. Keep at it, and your speed and accuracy will come. It requires only a well-planned strategy with a dedicated effort to enable you to excel in your Chemistry exam, setting a very strong base for your studies in the future. Keep yourself motivated, be consistent, and believe you can do it. Good luck!
The major topics asked in the paper are Solid State, Solutions, Chemical Kinetics, Coordination Compounds, the branches of Organic Chemistry, that is, Haloalkanes and Haloarenes, Alcohols, Phenols, Ethers, Aldehydes, Ketones, Carboxylic Acids, Polymers, Thermodynamics, Electrochemistry and Chemical Equilibrium.
The 2024 Chemistry paper introduced concepts at higher levels in different topics, such as the various crystal types in Solid State, complex scenarios on colligative properties in Solution, and advanced techniques of polymerization in Polymers. Also added were practical questions or experiment-based ones to infuse application-based learning.
The 2023 paper inclined more toward the practical applications of organic reactions, tending specifically to their usage in pharmaceuticals and other petrochemical industries. Other than that, it puts a focus on the solubility product and common ion effect in the Solutions and practical aspects of reaction kinetics in Chemical Kinetics.
The 2022 paper focused on the basics—unit cells and packing efficiency in Solid State, basic concentration terminology in Solutions, and the basics of mechanisms in Organic Chemistry. The emphasis was also slightly given to basic nomenclature and bonding theories in Coordination Compounds.
The consistently recurring concepts are in the SOLUTION: areas of Thermodynamics, Electrochemistry, Organic Reaction Mechanisms, Coordination Chemistry, and Chemical Equilibrium. They are very central to the theme of chemistry and often tested to see if the student has a tight grasp of some of the more important principles.

Yes, you can repeat Class 12th from the Maharashtra Board, even if you passed in 2022 and took an improvement exam. You need to re-enrol in a school affiliated with the Maharashtra Board , submit the necessary documents, and pay the required fees. The student may also contact the Maharashtra State Board of Secondary and Higher Secondary Education for specific guidelines and procedures for repeating Class 12.
If you want to repeat the MSBSHSE HSC exam in 2024 , you will have to contact the Maharashtra State Board about your missing MSBSHSE improvement result . You can visit their official website or reach out to your previous school for guidance. You can register as a private candidate to apply, however, it is advisable to get the latest information from the MSBSHSE board directly.
Hello!

Hello aspirant,
There are many NEET-UG 2024 coaching hubs and online resources in India that charge astronomical fees for NEET preparations, but some students cannot afford these fees, and some aspirants prefer to advance their preparation without choosing a premium subscription with NEET free coaching 2024 resources.
The free coaching options for NEET UG 2024 are a great option for those candidates. NEET free coaching sessions aren't all that different from premium coaching, despite their promises to have superior guides for medical preparation. Candidates will receive better instructors during the NEET free lessons in 2024, much like the premium ones.
