Preparation of an organic liquid – practical video | 16–18 years

Find supporting resources including pause-and-think questions, technician notes, worksheets, and more at https://rsc.li/3E3yJF9

This video covers a wide-range of experimental techniques used to synthesise an organic liquid.

All specifications aimed at learners 16–18 years (eg A-levels in England, Wales and Northern Ireland, Scottish Higher and Advanced Highers and the Republic of Ireland Leaving Certificate), include some form of synthesis of a pure organic liquid or solid.

You will need to appreciate that organic synthesis can involve multiple reactions, followed by extraction and purification steps.
