Three alcohol bottles were mislabeled in the stockroom: 1-pentanol, 2-pentanol, and 3-pentanol. A clever student decided to using MS to determine the identity of the structures. Using the MS data, draw the structure of the compound found in each bottle. Bottle #1: Base peak with a m/z of 45 Bottle #2: Base peak with a m/z of 70 and two significant peaks with m/z of 42 and 31 Bottle #3: Base peak with a m/z of 59

During an assay of paracetamol by UV an analyst prepares a series of calibration solutions containing approximately 3-15 mcg/mL paracetamol as follows: 140.1 mg of pure paracetamol was added to a 200 mL volumetric flask. 0.1 M NaOH (50 mL) was added, the mixture well shaken and made up to volume with deionized water 10 mL of the above solution was diluted to 100 mL 1)What is the concentration of the final diluted solution in mcg/mL?(1 decimal) 2) What volume of the diluted solution is required to prepare 100 mL of a 8 mcg/mL standard solution? (1 decimal)

A) What are the basic principles underlying TLC technique? B) Draw a TLC plate and explain how TLC can be used to identify the presence of a specific compound in an organic mixture.
Consider a sample that is a mixture composed of biphenyl, benzoic acid, and benzyl alcohol. The sample is spotted on a TLC plate and developed in a CH2C12-cyclohexane solvent mixture. Predict the relative Rf values for the three components in the sample. Would biphenyl be closest to the blotted line, then benzyl alcohol, then benzoic acid because these others are increasing in polarity to the non-polar solvent? Thanks!
4. You are developing a GC method to separate xylene isomers (xylenes are benzene rings with two methyl groups, which can be oriented ortho, meta, and para to each other). In the first run, the peaks come out too close together. If you want to increase retention, you should: a) Run the column at a higher temperature b) Run the column at a lower temperature c) Inject a larger volume d) Inject a smaller volume e) None of These
