1.	What is the full form of PCB(in the context of chemistry)?(a) Printed Circuit Boards(b) Polychlorinated biphenyls(c) Polychemical biphenyls(d) Primary Chemical BacteriaThe question was posed to me by my college professor while I was bunking the class.I'm obligated to ask this question of Environmental Chemistry in chapter Environmental Chemistry of Chemistry – Class 11
Answer» Correct option is (b) Polychlorinated biphenyls Best EXPLANATION: The full form of PCB is Polychlorinated biphenyls. It is used as a cleansing solvent. PCBs are also suspected to be carcinogenic (can lead to cancer). BACTERIA responsible for degrading BIODEGRADABLE detergent feed on these and grow RAPIDLY. While growing, they use up all the oxygen dissolved in water. Thus, the lack of oxygen kills all other forms of aquatic life such as FISH and plants.
