Iodoform test of acetone

The famous iodoform test is here. Carbonyl compounds having ketomethyl group gives yellow crystalline ppt of CHI3 with characteristic clinical smell. This is a wonderful reaction and very useful for distinguish purpose.

Sir, your precision in choosing appropriate words, length of explanation and conducting the experiment is commendable. Fantastic video!

[@insightsofchemistry-withsa9009]

Thank you so much... I am trying to improve... Actually I am not at all good in video editing... It's only a smart phone and a boya mic that's all I have... Anyway I am also learning. People like you encourage us for betterment. Thank you... ☺☺

thank you so much sir
for such a great explanation

Thanks sir for such a great explanation

[@eduardotomaslagosmolina5271]

I will try this variation as I failed to obtain a good yield using another technique.

[@rimpa9966]

Very nice Vedio sir. . Very useful

[@angelicajoven3310]

Sir, can you explain the principle behind how/why did the acetone gave positive result in iodoform test? Thank you!

[@insightsofchemistry-withsa9009]

Any carbonyl compound having ketomethyl group (CH3CO-) gives positive response to iodoform test. For details, you have to see the mechanism.

[@Anonymous-lf8dd]

Should the NaOH solution be conc. or dil. ?

[@insightsofchemistry-withsa9009]

Dilute.. But not very dilute.. Moderate concentration rather

[@طريقالتوبه-س3غ]

And calculate the yeild to idoform

[@طريقالتوبه-س3غ]

What the adventage from NaOH add for synthesis idoform

[@lakshmir2358]

don't use plastic gloves while heating. plain yellow was not visible

[@insightsofchemistry-withsa9009]

Thanks for the suggestions... Will try to follow it.. 🙂🙂

[@jassalji4126]

Sir will u please clear my doubt that ......what is the need to make the solution alkaline ??

[@insightsofchemistry-withsa9009]

See the mechanism of haloform reaction. It is a base catalysed reaction. The acidic alpha hydrogen of acetone must be abstracted by a base and that is why alkaline medium is necessary.

[@jassalji4126]

@@insightsofchemistry-withsa9009 thanku sir now i understand that it is the first step for the propagation of reaction in which hydroxyl group will act as nucleophile and remove abstract a alpha hydrogen so that reaction can proceed further. Thanks sir for ur reply 😇

[@insightsofchemistry-withsa9009]

@@jassalji4126 for the first three steps OH will act as base and in the fourth step it will act as nucleophile to attack the carbonyl carbon and CX3(-) will be released as leaving group to give the haloform CHX3

[@tabikhan6838]

What is normality of NaOH solution used here ??

[@insightsofchemistry-withsa9009]

It is 5(M) solution of NaOH
