Question

What was the purpose of using the rotary evaporator? How else could you have accomplished the same task, given enough time (that’s a hint!). Explain why your alternative method would work, and provide relevant data from your PC table.

Explanation / Answer

Organic chemistry

Rotary evaporator is used to remove solvent from the system.

Similar task can be achieved by using distillation technique, given enough time for the experiment.

The distillation also works on the same principle of removal of components by its volatility and hence this would work same as rotary evaporator technique.
