The iodoform test (or tri Iodomethane test) is used to identify the presence of 2 particular structural units:
1)RCH(OH)CH3
2)RCOCH3
*R denotes H, alkyl or aryl group
In positive tests, the reaction will produce a yellow precipitate of CHI3.

Any compound which contains the above mentioned structural units will result in a positive iodoform test. Ethanol is the only first degree alcohol to give a positive iodoform test.

great explaination please if you can send more experimaetns that reffers to ORGANIC CHEMISRTY to my Email marwahlutfi@gmail.com
thank you! have a nice day !
i hope you cited more examples of compounds that give positive iodoform test and explained why. :(
