In iodoform test can you use ethanol instead of water?
no, because ethanol gives iodoform reactions
What is the primary alcohol which gives iodoform test?
Ethanol is the only primary alcohol to give the iodoform test due to the presene of methyl group attached to alpha carbon atom.
Will methanol give a positive result in iodoform test?
Iodoform test is valid only for ethanol.
What is the positive test for iodoform test?
Hi, Iodoform test is used for the detection of methyl ketones as methyl ketones give positive iodoform test. In this test, methyl ketone is treated with iodine (I2) in the presence of base such as sodium hydroxide (NaOH) to give iodoform(CHI3 - a light yellow coloured ppt). Chemistry of iodoform test is: Secondary alcohols also give positive iodoform test because during the reaction conditions, it gets oxidized to a methyl ketone.
What test is used to show the reducing property of an aldehyde and a ketone?
tollen's test, fehling's test, iodoform test

What is the structure of C8H8O compound which gives a positive test of iodoform test and reacts with sodium almagam to yield C8H10O which gave negative iodoform test?
Structure of phenyl acetic acid (C8H8O2) is attached below.

Why would vanillin test positive in a ferric chloride test?
It would test positive because there is a phenol group in vanillin.
What is a test for presence of coch3 group?
Use an Iodoform test
What test is used to show the reducing property of an aldehyde and a ketone?
tollen's test, fehling's test, iodoform test
Is vanillin positive in a ferric chloride test?
yes
Is vanillin positive in tollens test?
No.While vanillin is an aldehyde, which should react with Tollens' reagent to precipitate silver metal, vanillin does not "pass" Tollens' test. Tollens' reagent is very basic (sodium or potassium hydroxide). Vanillin has a phenolic hydrogen (OH bonded to a phenyl ring) which is slightly acidic. Vanillin will react first with the excess hydroxide ions in solution to form a phenoxide salt, which will not participate in the silver-precipitating reaction.
Why only methyl ketones give iodoform test?
it is a ketone CH3CO group in carbonyl compound
What are the uses of iodoform?
Iodoform is used as a disinfectant, ear-hair remover, and it is used in packaging.
