Testing for organic functional groups: unsaturation or double bonds
words matched: functional, group
Many 16+ curriculums include testing for organic functional groups. The iodoform reaction is a simple test for the presence of the acetyl (ethanoyl) group (CH3CO–). The reaction can also be used to te..
