Synthetic Organic Chemical Industries

This set of MCQs helps students to learn about synthetic organic chemical industries in which we had man-made (anthropogenic) organic compounds created through industrial synthesis. Some SOCs evaporate easily (are volatile) whereas others tend to remain dissolved in water or other solvents with little or no evaporation.
