organic practical questions

synthesis of an organic solid

heated under reflux

• draw a labbeled diagram

synthesis of an organic liquid

heated under reflux

• draw a labeled diagram

seperation of an organic solid from liquid

filter under reduced pressure

• draw diagram

speration of two organic liquids

seperating funnel

outline the procedure of separating two liquids

• separate the immiscible liquids by using a separating funnel

• then add an anydrous salt to the organic layer (top layer)

• and dry at 90 degrees

purification of organic solids

via recrystalisation

how would you collect a pure sample of a solid

• add minimum amount of hot solvent

• cool

• crystals form

• filter under reduced pressure

• wash with little cool solvent

• dry

purification of an organic liquid

• distillation

• be able to draw this

how would you measure purity of an organic solid

• assess the boiling point and compare it to known values

• impure substances will have a wider range and a lowe melting point due to there being irregular packaging due to the range of intermolecular forces

how would you measure purity of an organic liquid

thin layer chromatography

can also work for solids
