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
Violet 2. A sample of hydrogen is heated up to produce the absorption spectrum which has four dark bands as shown below. We are going to explore the energy and wavelength associated with the dark band indicated by the arrow. For the dark band indicated by the arrow above, the electron transition that corresponds to this band results in an electron transition between n=2 and n=3. Draw an energy diagram to help you construct a step-by-step description for the processes involved to create this band in the absorption spectrum. Red

Hi sir Please solve question 13
a. Using the different green coloured atom centres to represent the different halogen atoms (F, light green; Cl, mid-green; Br, dark green), build a model of CHFClBr.b. Build a second model of CHFClBr which corresponds exactly to the mirror image of your first model.c. Try to superimpose the two models over one another – is there any way you can arrange the two models in such a way that all the different atoms in the two models are in the same place? Are they superimposable?d. Using wedge and dash bonds draw the structure of both models.e. Use the Cahn-Ingold-Prelog sequence rules to assign the absolute configuration of each compound.
What is the meaning of the term wavenumber, which is used in IR spectroscopy? OIt is the total number of wavelengths of IR radiation absorbed by the compound. It is the number of waves that pass through a particular point each second. It is another term for the energy of radiation. OIt is how many waves the IR light contains.
