Answer #1

Fractional distillation is a technique which is used to separate the liquids which have difference in their boiling points.

When the flask containing mixture of liquids is heated , the liquid having lower boiling point vaporises , passes through fractionating column into the condenser and collects into the beaker.

The liquid having higher boiling point vaporises later.

The temperature at which the liquid begins to boil and vaporise is noted down for both the liquids , and is considered their boiling points.

During last week’s lab of distillation, many of you had difficulties getting the fractional distillation column to work properly. Specifically, the liquid started condensing at the top of the fractional column and the vapor did not distill over. The lab instructor suggested that changing the bead size (which was in the column) to a larger size might improve the outcome of the experiment. Is this suggestion valid? Would it help the process or is this suggestion wrong? Explain your answer

1. A mixture of immiscible liquids (both water-insoluble) is subjected to steam distillation. At 90°, the vapor pressure of pure water is 526 mm Hg. If the vapor pressure of compound A is 127mm Hg and that of B is 246 mm Hg at 90°: (a) What is the total vapor pressure of the mixture at 90°? (b) Would this mixture boil at a temperature above or below 90°? (c) What would be the effect on the vapor pressure and...

Jack Slapdash was responsible for preparing the mixture for fractional distillation. He noticed after the distillation was complete that there was both 2-pentanone and 3-pentanone in the hood and he is not sure which one he actually used. After the distillation was complete he took a carbon nmr spectrum of his pot residue (pentanone) and noticed that there were only three signals after the solvent and reference signals were identified. Did Jack use 2-pentanone or 3-pentanone for his experiment? Explain...
