PYQ Mock: IIT JAM 2024 Chemistry (CY) Section A

IIT JAM 2024 Chemistry (CY): the 29 single-answer questions of Section A from the official paper, shown as pictures of the original questions. Choose A, B, C or D as printed in the picture. Q.1 to Q.10 carry 1 mark and Q.11 to Q.30 carry 2 marks, so the maximum here is 48. A wrong answer costs one third of the question's marks (shown as -0.33 and -0.67); an unanswered question scores zero. 1 single-answer question (Q.13) is left out because the official key does not give one correct option. The multiple-select and numerical-answer questions of Sections B and C cannot be answered in this exam room and are not included. 90 minutes is the practice time; the real paper has 60 questions in 3 hours. The official site no longer hosts the 2024 answer key, so the answers follow a public copy of the official master key (https://cdn.aglasem.com/aglasem-doc/8308cdac-315a-11ef-923e-0a5e36bc6706/8308cdac-315a-11ef-923e-0a5e36bc6706.pdf). They were matched by question number by software and are not expert-verified; use the official key if you spot a difference. Original paper: https://jam2026.iitb.ac.in/files/CY2024.pdf. The paper belongs to the JAM organising institute and is shown for practice with credit.
