Explain how the colours in a orange drink samples become separated on the chromatography paper?

Colour has different distribution so therefore it is carried further.

Describe on similarity and one difference between thin layer chromatography and paper chromatography.

Similarity- different solutes travel different distances.

Difference- medium is different

Suggest why scientists use thin layer chromatography instead of paper chromatography.

Permanent felt tip ink does not dissolve so it would not travel well on paper.

Which two types of organic compound react together to make an ester?

Alcohol and Carboxylic acid.

Few esters used be flavor foods are extracted from fruits. Most of these esters are produced by chemical synthesis. Suggest why

-synthesis is cheaper

-extraction from fruits are more complex

-fruit takes a long time to grow
