Coordination Compounds JEE Questions PDF with Solution, Practice Now

Coordination Compounds JEE Questions: Coordination compounds are a group of chemical compounds formed when a central metal atom or ion is bonded to a set of surrounding molecules or ions known as ligands. For JEE aspirants, the coordination compounds in the JEE Main syllabus is a scoring one if well-studied. The JEE exam generally asks a few questions based on the fundamental concepts of coordination chemistry, such as naming, bonding, isomerism, and stability of coordination compounds. Practicing coordination compound JEE Questions will help the aspirants to revise the important topics/concepts, which can help in scoring points while solving numericals and other problem-solving questions based on these topics/concepts.

Coordination Compounds JEE Questions Overview

Coordination compound JEE questions are generally asked in the JEE Mains and JEE Advanced exam inorganic chemistry section. In general, JEE Mains questions related to coordination compounds are quite straightforward and test the conceptual understanding of the students. At the same time, the JEE Advanced inorganic chemistry questions on coordination compounds can be quite tricky and involve a combination of multiple concepts.

Previous year paper analysis indicates that approximately 2–3 questions based on coordination compounds are asked every year. Many important coordination chemistry JEE questions are related to naming, hybridization, magnetic properties, and the types of ligands.
