Q9. The insecticide DDT (in the box below) is useful in controlling mosquito populations and haslow toxicity to humans, but is dangerous to birds and fish. Hoping to alleviate the dangers, littleJohnny Whizbang, an aspiring chemist, proposes a new version of DDT ("Bromo-DDT") andshows his synthesis to his boss. Will Johnny Whizbang's synthesis work? Or will he be fired?Assume there is an excess of bromine and polybrominated products can be separated.

3. A midnight dumper discharged a tank truck full of industrial waste in a gravel pit. The truck was spotted there 3 days ago, and a pool of pure waste remains. A laboratory technician determined that the waste has a 5-day BOD of 80 mg/L with a rate constant of 0.1/day. Three factories in the vicinity generate organic wastes: a winery (ultimate BOD = 275 mg/L) a vinegar manufacturer (ultimate BOD = 80 mg/L) and a pharmaceutical company (ultimate BOD = 200 mg/L). Using the information, determine the source of the waste.

Prof. Neiman and Prof. James were first to discovered in 1973 that chlorofluorocarbons (CFCs) were depleting the Earth’sozone layer when released into the atmosphere. Once they reach the stratosphere, Clis released from the CFCs molecules by interaction with UV light. Free Cl atoms areable to react with ozone in a catalytic cycle that converts O3into the more stable O2.It is estimated that a single Cl atom is able to react with∼100000 O3molecules.Although CFCs production was banned in 1996, there are still a substantial numberof motor vehicle air conditioners (MVACs) that use CFC-12 (CF2Cl2) as refrigerant.The average CFC-12 emission rate from operating MVACs has been estimated tobe 59.5 mg per hour per vehicle (Zhang et al.Environ. Sci. Technol. Lett.2017).How much chlorine, in kg, is added to the atmosphere in a year due to 100 millionMVACs using CFC-12 as refrigerant?
