The Problem Set section provides a systematic collection of graded questions designed to reinforce conceptual understanding, numerical accuracy, and exam preparedness. This module is suitable for Class 11–12 students, undergraduate learners, and competitive exam aspirants, covering difficulty levels from basic recall to advanced reasoning.

In this section, you will practice:

• Conceptual MCQs on transition element characteristics and d-block trends

• Electronic configuration and oxidation state problems

• Short-answer questions on variable valency, color, and magnetism

• Coordination compound nomenclature problems (basic IUPAC)

• Ligand identification and coordination number questions

• Magnetic moment and unpaired electron numericals

• Geometry and hybridization determination problems

• High-spin vs low-spin classification questions

• Assertion–reason and multi-statement MCQs

• Mixed-concept problems integrating transition metals and coordination chemistry basics

• Exam-pattern questions aligned with school exams, NEET, JEE, CUET-UG, and UG assessments

Problems are arranged in increasing order of difficulty, enabling learners to build confidence progressively, identify conceptual gaps, and improve speed and accuracy.

Consistent practice with this problem set will ensure a strong command over Transition Elements and Coordination Chemistry (Basics) and prepare students for advanced inorganic chemistry chapters and competitive examinations.
