DISTILLATION

Front

What is fractional distillation?

Back

A method used to separate components of a mixture with close boiling points, involving a fractionating column above the distillation flask.

What is distillation?

Back

A process for separating components of a mixture by evaporating and then condensing the vapors.

Front

What is simple distillation?

Back

A method used to separate components with greatly different boiling points or to separate volatile from nonvolatile components.

What is the primary use of distillation in organic chemistry?

Back

To purify organic compounds.

Front

What is the principle behind distillation?

Back

It relies on differences in boiling points to separate components of a mixture.

Front

What equipment is commonly used in fractional distillation?

Back

A fractionating column.

Front

What is the difference between simple and fractional distillation?

Back

Simple distillation is used for mixtures with significantly different boiling points, while fractional distillation is for those with close boiling points.

Front

What is the role of a condenser in distillation?

Back

To cool and condense the vapor back into liquid form.
