Homework Answers
(a): Since both CCl3 and C(CH3)3 have similar size, the insecticidal property will exist, but it will decrease many fold. Because -Cl atoms are responsible for insecticidal property. Hence -CCl3 has highest insecticidal property.
(b): The insecticidal property in DDT is mainly due to those those two para-Cl atoms. Hence when we replace them by H atoms, there will be no more insecticidal property.

6. Usually, hydrogen atoms are to evolved ways of stabilizing what such as the following (part of the ci rogen atoms are terrible leaving groups. However, biological enzymes have ays of stabilizing what would otherwise be a poor leaving group, resulting in reactions ne following (part of the citric acid cycle). The reaction follows an E2 mechanism, and we expect that the hydrogens that are removed must be anti to each other. We can prove hypothesis by performing the reaction...

Week 10- Constitutional isomers Constitutional isomers have the same molecular formula, but their atoms are bonded in different orders. These may be further distinguished as chain isomers, which differ only in hydrocarbon chain structure, positional isomers, which differ in the location of a functional group, and functional group isomers which differ in the nature of their functional groups. Typically chain and position isomers show only modest differences in their physical and chemical properties, while functional group isomers differ greatly from...

3. Cyclic compounds The presence of the ring in all but very large ring cyclic molecules prevents full rotation of the ring atoms. For this reason, stereoisomerism may also occur in cyclic molecules. a) Prepare a model of cyclohexane, C6H12. Draw the condensed formula. b) Build a model of methylcyclohexane (C7H14) by replacing one of the hydrogens of cyclohexane with a methyl group. Draw the skeletal formula for methylcyclohexane. 2 c) How many different isomers exist for methylcyclohexane (CyH34)? d)...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
