Determine the structure of the six compounds whose IR and PMR
spectra are provided on the attached sheets, given the following
comments about the provided information and spectra.
PMR Spectra: The PMR spectrum of each compound is provided,
along with peak areas. The peak areas are given as the simples
whole number ratio of protons and are indicated (for exmpale, 4H).
Your final structure must be consistent with the chemical shift...

Hints for identifying compounds in multiple-choice problems (problems 1:5); 1. Closely compare the given compounds. Determine which piece of information (molecular weight from MS, number of peaks in the NMR, presence of a special functional group in the IR, etc) would be the easiest for distinguishing between the given compounds. You might not need to use all types of given spectra to find your correct compound! 2. Based on your answer from step 1, consult the appropriate spectrum first. For...

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...
