3) Which of the following molecules would match the IR spectrum shown? Justify your answer. 100- 4000 3403 3083 D) m NHCH,CH, B) 2005 D NHCH,CH, 1004 1503 1500 Wennber -CH₂CH₂OH E) 8 1000 749 CHINH, m CH₂CH₂OH Now, let's think about IR in the context of a chemical reaction. Whenever you're trying to figure out what happened in a particular reaction, you need to consider two separate factors: 1) Did the product appear? 2) Are any other possible, unwanted compounds (most often the starting material) still present? Both of these are important (although students generally focus only on the first question) - we want to make sure that our product is not just present, but pure.

Counterfeit drugs are a common problem in developing regions of the world. Oftentimes, counterfeit pills are made with compounds such as lactose. A lab technician has obtained the IR spectrum shown above for a sample reported to be citalopram, an antidepressant drug. Does the IR spectrum belong to citalopram or lactose? Explain your answer by describing what feature of the IR spectrum confirms your choice and describe what feature is missing from the IR spectrum for the other compound. A. citalopram B. lactose

orgo chem II nmr  please help me fill out this chart!

Using the following spectra and other information provided, identify the compounds, and all pertinent peaks are assigned in the spectra (correct compound, labeling proton spectrum, labeling carbon spectrum) Label the peaks on the spectrum and place the structure of the compound in the box on the right side of the spectrum.

Sorry that it is sideways. The question is asking which compound is represented in the IR spectrum, and why. I’m just really lost on interpreting these.

3. Protons A-E are identified on the spectrum below and correspond to the five unique protons in the molecule shown. (a) Place all the protons on the molecule and categorize them into Ha, Hb, etc. (b) Fill in the table for this molecule (see answer sheet). E الاس D N PPM B 72 A

#2) Using the following spectra and other information provided, identify the compound. Assign pertinent peaks in the spectra. Label the peaks on the spectrum and place the structure of the compound in the box on the right side of the spectrum - Identify correct compound - label proton spectrum - label carbon spectrum
