Analyzing and Predicting Spectroscopic Data

The interaction of electromagnetic radiation with the structure of molecules in the sample and their study is referred spectroscopy. Several spectroscopic methods are used to acquire sample information, and these methods are proved to be accurate, fast, and non-destructive. The information obtained about the content and composition of molecules from these spectroscopic methods is called spectroscopic data.

What is the purpose of including a melting point in a procedure? A) As a method of purification - We can purify a substance. B) As a method of encouraging synthesis - Reagents are always more reactive in the liquid state. C) As a method of encouraging a substance to dissolve - Free molecules in the liquid state can make interactions and dissolve in the solvent easier. D) As a method of characterization We can identify an unknown substance. -- O A OD
Background: Given an unknown mixture which contains either two or three of the following liquids: tetrahydrofuran (THF), cyclohexane, toluene, and o-xylene. While the order that the compounds leave the column is not always obvious, the column we are using is a polar environment and therefore we would expect less polar (lower boiling) compounds to spend the least time in the column. In order to qualitatively confirm the identity of the peaks, you will make five different samples to analyze on the gas chromatograph: (a) your unknown, (b) unknown + THF, (c) unknown + cyclohexane, (d) unknown + toluene, and (e) unknown + o-xylene. Any new peak that appearsin relation to your unknown sample indicates that compound is not present in your unknown; furthermore, an increase in the size of a peak present in your unknown identifies that compound as a component of the mixture. Although not completely accurate, the areas of the peaks in your unknown will allow you to find the approximate percentage…
Problem: If the diameter of a bicycle wheel is 622 mm, what is the diameter of the wheel in inches? (1 inch = 25.4 mm) Solution: 622 mm x 1 inch/25.4 mm = 24.5 inches. Make sure to show all the units in your solutions, as seen in the example above.
