What else can I help you with?
Will methanol give a positive result in iodoform test?
No, methanol will not give a positive result in the iodoform test. The iodoform test is specifically used to detect the presence of compounds with the CH3CO- group in them, such as methyl ketones, which are required for a positive reaction.
Does vanillin gives iodoform test?
Yes, vanillin can give a positive iodoform test. The iodoform test is used to detect the presence of a methyl ketone group attached to a carbon atom adjacent to two other carbon atoms, and vanillin has a structure that can undergo this reaction.
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.
Is iodoform soluble in water?
no it's very very sparingly soluble in water .......iodoform soluble in alchol and chloroform .............
Why this test is positive only for ketos?
Do you mean ketones? Ketones are a by-product of fat breakdown. When a person is not eating enough carbohydrates (bread, pasta, rice, potatos) for their energy needs the body starts using its fat stores for energy and ketones show in the urine. It may also be a sign of diabetes. If I haven't answered the question you asked please ask as something different.

What are the chemical tests to distinguish between 2 pentanone and 3 pentanone?
Do an iodoform test. Use an aqueous solution of iodine and potassium iodide added to basic solutions of 2-pentanone and 3-pentanone.The iodoform reaction is a classical test for methyl ketones. A light-yellow precipitate of iodoform forms immediately with the methyl ketone of 2-pentanone.To confirm:1H NMR3-pentanone will show only 2 signals: a triplet at ~1.33 and a quartet at ~2.352-pentanone will show 4 signals: a triplet at ~0.90, a sextet at ~1.55, a singlet at ~2.05 and a triplet at ~2.40

How does ketones react with sodium bicarbonate?
Ketones or Aldehydes DO NOT react with Sodium Bicarbonate..generally only Carboxilic acids have the ability to do it!
What molecule has only one element?
Carbon Dioxide,Carbon Monoxide,Carbonic Acid,Sodium/Potassium/Calcium Carbonate,Sodium/Potassium/Calcium Bicarbonate,Methane,Methyl Alcohol,Formaldehyde,Formic acid,Sodium/Potassium/Silver Formate,Diazo-methane,Carbon Tetrachloride,Chloroform,Iodoform,Methyl Bromide/Chloride/Iodide,Dichloromethane,Methyl Cyanide,Sodium Methoxide,etc.

Why do aldehydes and ketones add only one equivalent of Grignard reagent?
Aldehydes and ketones add only one equivalent of Grignard reagent because the reaction forms a stable intermediate that prevents further addition of the reagent.
Why is there no number needed for the methyl branch in methylcyclobutane?
In the case of methylcyclobutane, there is only one possible position for the methyl group, which is at the carbon attached to the ring (the only carbon available). Therefore, a number is not needed to specify the location of the methyl group.
What kinds of alcohols can be used to prepare ketones?
Primary or secondary alcohols can be used to prepare ketones through oxidation reactions. Common methods include using mild oxidizing agents like chromic acid, PCC (pyridinium chlorochromate), or Swern oxidation. Tertiary alcohols cannot be oxidized to ketones.
What is used to supply some of the fuel needed by the brain only after the body has been fasting for a while?
Ketones
