Fractional Distillation Concepts

Front

Where do Smaller fractions condense?

Back

Higher up the column.

Front

What process is taking place at A?

Back

Evaporation.

Front

Vapour rises up the fractional distillation column, is the column is cooler or hotter at the top?

Back

Cooler

Front

Long-chain hydrocarbons have higher boiling points due to....?

Back

They have stronger intermolecular forces, so more energy is needed to overcome them.

Front

A fractional distillation column is hottest at...

Back

The bottom

What do hydrocarbons in each fraction have in common?

Back

Number of carbon atoms and boiling point
