This PDF contains the Chemistry section of the JEE Main 2024 question paper, conducted on 27 January, Shift 1. It includes Section A multiple-choice questions along with detailed exam instructions and marking scheme. The questions are designed to test conceptual understanding, application skills, and clarity of fundamentals across physical, organic, and inorganic chemistry.

I am writing about this paper because analysing an actual exam paper gives students a clear idea of how questions are framed and which areas are given priority. Instead of guessing trends, this document shows exactly what appeared in the exam and how the syllabus was translated into real questions.

Structure of the Chemistry Question Paper

As per the PDF, the Chemistry paper is divided into two sections. Section A consists of 20 multiple-choice questions, each carrying 4 marks, with a negative marking of 1 mark for incorrect answers. Section B consists of 10 numerical value type questions, out of which candidates are required to attempt any five. Each numerical question carries 4 marks with no negative marking.

The instructions clearly mention time duration, marking rules, and the method of entering numerical answers, making the exam format transparent.

Organic Chemistry Questions in Shift 1

Several questions in Section A are based on organic chemistry concepts. One question tests understanding of nucleophilic substitution reactions in chiral alkyl halides, directly comparing SN1 and SN2 mechanisms and their stereochemical outcomes such as racemisation and inversion.

Another organic chemistry question focuses on IUPAC nomenclature, asking candidates to correctly name a substituted cyclohexane compound. This tests clarity in numbering, alphabetical order of substituents, and correct application of naming rules.

Inorganic Chemistry Focus Areas

The paper includes questions from inorganic chemistry, particularly periodic classification and block elements. One question compares two statements, one related to placement of 4f and 5f series in the periodic table, and the other related to availability of s-block elements in nature. This type of question tests both conceptual understanding and factual accuracy.

Another inorganic question involves chromyl chloride test, where candidates must identify the reddish fumes formed when sodium chloride reacts with potassium dichromate and concentrated sulphuric acid, and the yellow compound formed after reaction with sodium hydroxide. This checks knowledge of qualitative inorganic analysis.

Acid–Base and Chemical Reactivity Concepts

The PDF also includes a question asking for the strongest Brønsted base among given nitrogen-containing species. This requires understanding of basicity trends, lone pair availability, and resonance or inductive effects.

Such questions are concept-based and cannot be solved by rote memorisation, highlighting the exam’s emphasis on understanding fundamentals.

Question Style and Difficulty Level

Based on the Chemistry questions visible in the PDF, the paper maintains a balanced difficulty level. The questions are not overly lengthy but require clarity of concepts. Many questions are direct but framed in a way that tests precision, especially in organic mechanisms and inorganic reactions.

The use of assertion–reason type logic, reaction-based questions, and statement analysis reflects the standard JEE Main approach.

What This Paper Reveals About Exam Trends

The Chemistry section of JEE Main 2024 Shift 1 shows that:

• Conceptual clarity is prioritised over lengthy calculations
• Organic reaction mechanisms and stereochemistry are important
• Inorganic qualitative tests remain relevant
• IUPAC nomenclature continues to be a scoring area
• Statement-based questions test deeper understanding

This paper reinforces the importance of NCERT-based preparation with strong conceptual grounding.

The JEE Main 2024 Shift 1 Chemistry paper, as seen in this PDF, is a well-structured and concept-focused exam. It tests a wide range of topics through concise but thoughtful questions. For aspirants, analysing this paper helps in understanding exam expectations, identifying important topics, and refining preparation strategy. Studying such real exam papers is one of the most effective ways to improve performance in future attempts.
