Question
Dichlorodiphenyltrichloroethane is the chemical name for the pesticide DDT. What is the most likely class of compound for DDT? alcohol amine carboxylic acid organic halide none of the above You are removing your battery from your car and a loose cap allows the liquid to get on your shirt. And what immediate action would you take for the spill? What might the liquid be? Why do automobiles use this type of acid? You are a plant operator in a chemical plant. During your rounds you notice the waste has a sheen-like film on the top layer. What steps would your take? How would you help solve this problem?Explanation / Answer
21. DDT contains Cl groups and ethane is a hydrocarbon. It does not contain any other functional group like carboxylic acid, alcohol or amine. So, overall DDT is organic halide.
22. Immediate action after spilling the liquid would be wash it with water. Whether it is acid or base, water will dilute it and thus decrease its effect on body or clothing. The liquid might be an acid. The acid acts as an electrolyte in the battery in which anode and cathodes are dipped. The acid will allow the electrons to flow between the electrodes.
23. The sheen like layer on the top of the waste water coming from chemical plant is oil or organic compounds which are insoluble in water. Initial step to be taken is to check the process in the plant which is producing this kind of water and making modifications in the process which will not produce this kind of water. The problem can be solved by using some adsorbent which can adsorb this whole oil layer.
