This chapter is about Organic Chemistry. Before 1828, it was thought that Organic Compounds can&#8217;t be manufactured by an inorganic material. But this theory was rejected by Friedrick Wohler. Organic compounds are those which contain carbon, hydrogen, and their derivatives. They have many salient features. They have much importance in our daily life. The sources of Organic compounds include Coal, Natural Gas, and Petroleum. Cracking and Reforming of Petroleum is done to increase its octane number. Organic compounds are classified into Open chain and Closed Chain compounds. Their shapes are defined through Hybridization. Isomerism is an important term that represents formulas of different organic compounds. So, have a look at this page to get the important MCQs of this chapter.<\/p>\n<h2 style=\"text-align: center;\">Chemistry 2nd Year Fundamental Principles of Organic Chemistry Mcqs<\/h2>\n<p><img
