MCQs for CBSE Class 12 Coordination Compounds: This article of Jagran Josh brings you a set of important Multiple Choice Questions for the chapter Coordination Compounds of Class 12 Chemistry. The MCQs part of the paper in CBSE Board Exams is the highest scoring one as each correct answer will fetch you 1 mark without any deduction. But solving MCQs can be tricky at the same time as questions can be asked from any part of the textbook and can be based on any concept that would seem to be of least importance. MCQs are actually included in CBSE exam pattern to assess students on the basis of their concept knowledge along with their critical and analytical thinking skills.
MCQs provided by Jagran Josh are the best resources to practise a variety of questions which are created by subject matter experts. All the questions are based on the revised CBSE syllabus and are made to cover all the concepts discussed in the chapter. So, practising with these MCQs can be really helpful in your CBSE Board Exam 2024 preparations. You can check all the MCQs for CBSE Class 12 Chemistry Chapter 5 – Coordination Compounds below.
