You want to make a solution of a solid sample for IR analysis. Assuming that the solid dissolves in it, why would carbon tetrachloride be a good solvent to use?
Homework Answers
CCl4 is the best solvent used in IR spectroscopy beacause it does show any absorption peaks more than 1000cm-1.The functional group region is around 1450cm-1 to 4000cm-1.so the ccl4 does not have peaks to show in the fingerprint region.
If water is taken as solvent in IR spectroscopy,O-H peaks may appear which coincides with the functional group peaks leads to wrong analysis.
CS2 is also a good solvent that is used in IR analysis

QUESTION 11 # 63. Carbon tetrabromide, CBr4, is used to make organic compounds, and carbon tetrachloride, CCL4, is an industrial solvent whose use is diminishing due to its toxicity. Both molecules are nonpolar. Carbon tetrachloride is a liquid at room temperature, but carbon tetrabromide is a solid, suggesting that the attractions between CCI4 molecules are weaker than between CBr4 molecules. Explain why

A solution of carbon tetrachloride and acetic acid CH3COOH is boiling at 107.6°C. A sample of the vapor above the solution is cooled until it condenses. This condensed sample is analyzed, and turns out to be 50.% carbon tetrachloride by mass. Calculate the percent by mass of carbon tetrachloride in the boiling solution. Here's some data you may need: normal boiling point density vapor pressure at 107.6°C carbon tetrachloride 77.°C 1.6gmL 1733.torr acetic acid 118.°C 1.1gmL 623.torr Be sure your...
