If you want to start preparing for the 2nd Year Chemistry Chapter 7 MCQs Principles of Organic Chemistry, then this is the place where you will find it. The study of compounds of carbon and hydrogen and their derivatives is called Organic Chemistry. This chapter is about studying the features of organic compounds, the importance of organic chemistry, and the sources of organic compounds. The most important concept in this chapter is the classification of organic compounds. There are some classes in which they are classified are open-chain or acyclic and closed-chain or cyclic compounds. Then there is the hybridization concept of molecules. The final concept is Isomerism. Now let’s have a look at the important MCQs for this chapter.
