Experiment 6 Testsfor Aldehydes and Ketones Both aldehydes and ketones have carbonyl group and thus have similar reactions due to this functiona group. The C-o double bond consists of a -bond and a bond. The electrons situated above an below the carbonyl plane are exposure, making the carbonyl bond reactive. Oxygen is more electronegative than carbon and the C-O bond is polar, more negative on...

Which of the following statements is NOT true about phenol? Select the correct answer below: The aromatic ring delocalizes and stabilizes the negative charge on the oxygen in the phenoxide ion. Therefore, phenols completely dissociate in water. A phenol will generally form stronger hydrogen bonds than nonaromatic alcohols because the oxygen-hydrogen dipole in the hydroxyl group is stabilized by resonance from the aromatic ring. The phenol functional group is a weak acid in water because the hydroxyl group dissociates slightly....

Indicate which of the following statements about the electromagnetic spectrum and IR spectroscopy are true and which are false. In any cases where the statement is false, explain how or why the statement is false. Infrared (IR) light is in the gamma ray part of the electromagnetic spectrum. Electromagnetic radiation is characterized by its mass and force. UV-Vis spectra are normally scanned in the 4000-600 cm-1 region. The fingerprint region on an IR spectrum is the easiest to interpret. Stronger...

Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
