GATE Chemistry Syllabus 2022

Chemistry is a part of Science, and the Chemistry Paper for GATE Exams is mentioned with code CY. Candidates who select this as their first paper get to choose between the two Papers, CH (Chemical Engineering) and XL (Life Sciences). Meanwhile, the Chemistry paper is also available as a secondary paper with the code XL-P. This is compulsory for the candidates that opt for the XL subject.

To get an idea about the topics covered under Paper 1 and Paper 2 of Chemistry for the GATE Exams, candidates can refer to this web page’s information and the PDF link provided below.
