Does acetophenone give iodoform reaction?
Table of Contents
Does acetophenone give iodoform reaction?
Solution : Acetophenone `(C_6H_5 COCH_3)` contains the group `(CH_3CO)` attached to the carbon atom and hence give iodoform test while benzophenone does not contain this group and hence does not give iodoform test.
Does acetophenone undergo iodoform test?
Solution : Acetophenone `(C_(6)H_(5)COCH_(3))` contains the group `CH_(3)CO` attached to carbon and hence gives iodoform test while benzophenone does not contain this group and hence does not give idoform test.
Does ethanol show iodoform reaction?
Which type of alcohol gives iodoform test? The only primary alcohol that provides the triiodomethane (iodoform) reaction is ethanol.
Which of the following will not give the iodoform test?( A acetophenone C benzophenone B Ethanal D ethanol?
thus,correct answer is C .
What are the 2 products of a positive iodoform test result of acetophenone?
In this typical iodoform reaction, acetophenone (a methyl ketone) is treated with aqueous NaOH and I2 to produce sodium benzoate and iodoform. The yellow precipitate confirms the presence of the methyl ketone moiety in acetophenone.
Which of the following does not give iodoform test ethanol?
The last compound i.e. 3 – pentanone does not contain the required functional group with the structure CH3−C=O. for the iodoform test. Therefore, 3 – pentanone does not give the iodoform test.
Which of the following alcohols does not give iodoform test?
Vinyl alcohol Was this answer helpful?
Does Ethanal give positive iodoform test?
Ethanal is the only aldehyde to give the triiodomethane (iodoform) reaction. If “R”is a hydrocarbon group, then you have a ketone. Lots of ketones give this reaction, but those that do all have a methyl group on one side of the carbon-oxygen double bond. These are known as methyl ketones.
Which of the following alcohols does not give iodoform reaction?
Which of following will not give iodoform test acetophenone?
Acetophenone (C6H5COCH3) contains the grouping (CH3CO attached to carbon) and hence given iodoform test while benzophenone does not contain this group and hence does not give iodoform test.
Which of the following will not give iodoform test ethanol?
Solution : Benzyl alcohol does not have the `CH_(3)CO-` group or `CH_(3)CH_(2)O^(-)` so it will not give the positive iodoform test.
Which of the following will not give the iodoform test acetophenone?
What gives a positive result in the iodoform test?
Using iodine and sodium hydroxide solution A positive result is the appearance of a very pale yellow precipitate of triiodomethane (previously known as iodoform) – CHI3. Apart from its color, this can be recognised by its faintly “medical” smell.
Which alcohols do not give iodoform test?
Which reaction will not give positive iodoform test?
only methanol does not give positive iodoform test.
Does Ethanal give iodoform test?
Ethanal is the only aldehyde to give the triiodomethane (iodoform) reaction.
Which of the following alcohols will show positive iodoform test?
propan-2-ol is CH3−CH(OH)−CH3 thus it will have −COCH3 group and hence gives a positive iodoform test.
Which will not give iodoform test ethanol?
It must be remembered that primary alcohols do not test for iodoform test. Ethanol is the only primary alcohol which gives the iodoform test. Also, the only aldehyde which will give the iodoform test is the acetaldehyde because it contains the desired functional group i.e. $ C{H_3} – C = O $ .
Which alcohol does not show iodoform test?
n butyl alcohol (CH3CH2CH2CH2OH) does not give iodoform test because it does not possess the CH3CO− or CH3CHOH group. Was this answer helpful?
Which compound will not give iodoform test?
Compounds containing either CH3C∣HOH or CH3C∣=O group, on reaction with NaOH and I2 form yellow coloured iodoform. This is called the iodoform test. Hence, C6H6OH does not give the iodoform test.
