Organic Chemistry Functional Group Unknowns 2012 Pre-Lab Questions The standards used in this experiment are acetone, isopropanol, benzyl alcohol, benzaldehyde, benzoic acid, phenol, 1-napthol, 4-nitroaniline and cyclohexene. 1. Draw the structure of each of the standards. 2.rganic Chemistry Functional Group Unknowns 2012 d. Jones Oxidation Test for Alcohols (1Ë and 2Ë) and Aldehydes ***Jones Reagent contains Cr(VI) which is carcinogenic. Wear gloves and handle with care.*** â¢ Perform the Jones test on acetone, isopropanol, benzaldehyde and your unknown.
1. A sound wave is a pressure wave; regions of high (compressions) and low pressure (rarefactions) are established as the result of the vibrations of the sound source. These compressions and rarefactions result because sound. a. is more dense than air and thus has more inertia, causing the bunching up of sound.
Sound waves create compressions in the air between two plates, and when two compressions meet at one point, it creates interference. When a drop of water, for example, is caught in the interference between these two varying frequencies, it starts to hover in mid-air.
