Which one among the following alcohols will give iodoform on treatment with iodine and sodium hydroxide?
propan-2-ol.
Which of the following alcohol will give iodoform test?
Ethanol is the only primary alcohol to give the triiodomethane (iodoform) reaction.
Which of the following will give iodoform test with I2 and NaOH?
When Iodine and sodium hydroxide are added to a compound that contains either a methyl ketone or a secondary alcohol with a methyl group in the alpha position, a pale yellow precipitate of iodoform or triiodomethane is formed. It can be used to identify aldehydes or ketones.
Which of the following alcohols will not give iodoform test?
Benzyl alcohol does not have the CH3CO- group or CH3CH2O- so it will not give the positive iodoform test.
Which of the following alcohol give Haloform reaction?
Ethyl alcohol is the only primary alcohol that gives positive haloform test. When methyl ketones are treated with sodium hydroxide and iodine, yellow precipitate of iodoform is produced which indicates positive haloform test.
Which of the following alcohols will give the most stable carbocation during dehydration?
The tertiary carbocation formed during dehydration of 2-methyl-2-propanol is most stable.
Does iodoform contain iodine?
Iodoform is an organoiodine compound with the formula CHI3 and a tetrahedral molecular geometry. … Iodoform is soluble in fatty acids and decomposes releasing iodine in nascent state (96,7% of iodine) when in contact with secretions or endodontic infections 2.
Which of the following gives iodoform reaction?
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.
How does ethanol give iodoform test?
Explanation: For the iodoform reaction to take place, the compound should contain , where R can be H or an alkyl group. Thus, ethanol gives a positive iodoform test. The compounds which give positive iodoform test are the ones with Alpha methyl groups.
Which one of the following will give positive iodoform test?
(CH3-C∣∣O),(CH3-CH∣OH-) groups gives positive iodoform test.
