Level 1 – 1H-NMR vs Hydrogen-Coupled 13C-NMR vs Decoupled 13C-NMR  When performing NMR using 1H-NMR, Hydrogen-Coupled 13C-NMR, and Decoupled 13C-NMR , which of the following is true?

Level 3 – Liquid Chromatography, the Larger Scale of TLC – Predicting Order of Eluents Four compounds were combined and added onto a silica gel column with a mobile phase of Dichloromethane (DCM). The compounds were: I: HexanolII: PropaneIII: 3-amino-hexanoic acidIV: 1,2-Pentadiol Predict the compounds elution order from last to elute to first to elute (ordered left to right below).

Level 1 – Mass Spectroscopy – Isotopic Ratios A student is examining a mass spectrum and has observed an m/z peak at 222 and 224 in a ratio of 3:1. What functional group is most likely present?

Level 2 Infrared Spectroscopy – Reading the Spectrum Given: A: B: C:D:    Which of the spectra above would best correspond to a Carboxylic Acid? (there is only 1 correct answer)

Level 2 – SN1, E1, SN2, E2  We’ve covered the essentials for SN1, SN2, and E1 reactions and determining how a set of reaction conditions will proceed involves ranking 3 factors: 1) The nucleophile/base2) The leaving group3) The solvent Focusing on these 3 factors, and recalling what we’ve discussed in the slides, which of the following is true?

When treating a patient with Multiple Sclerosis, a therapist performs the MiniBEST and finds that the patient has significantly impaired anticipatory postural control. Which of the following complaints might the patient report based on these findings?

An electron is moving as a free particle in the -x direction with momentum that has magnitude 4.50 x 10-24 kg m/s.  What is the one-dimensional, time-dependent wave function of the electron?

Photorefractive keratectomy (PRK) is a surgery process that can correct near- and far-sightedness by using a laser to remove part of the lens of the eye to change its curvature and hence focal length. The procedure can remove layers 0.25 m thick using laser pulses lasting 0.012 ps with a beam of wavelength 193 nm. a. (8points) In what part of the electromagnetic spectrum does this laser lie, and what is the energy of each photon? b. (6 points) What is the uncertainty in the energies of the photons?

Select True or False for each of the following statements: In GWAS, most statistically associated variants are causal/functional variants. In other words, most of the time a SNP allele at a statistically significant SNP locus will increase risk for the disease/phenotype being investigated by the GWAS. [false1] With GWAS it is relatively easy to detect risk variants that are rare with a small to moderate effect size using GWAS. [false2] A GWAS has the power to detect variants with very small effect sizes if the sample size is at least two thousand. [false3]
