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.
Does vanillin gives iodoform test?
No because vanillin is phenolic aldehyde (only acetaldehyde give idoform among all ketones)
Will methanol give a positive result in iodoform test?
Iodoform test is valid only for ethanol.
What is the chemical name for frankincense?
Frankincense is an organic resin, and a mixture of many chemicals - oils, boswellic acids, ketones and gum. It is therefore impossible to give a 'chemical name' for frankincense itself, only its many components.
Why fructose gives positive tollen reagent test?
Only aldehydes give a positive Tollens test. However, under the strongly basic conditions of the test, alpha-hydroxy ketones can isomerize to aldehydes, so they will also give a positive Tollens test. Fructose is an alpha-hydroxy ketone.

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
Will methanol give a positive result in iodoform test?
Iodoform test is valid only for ethanol.
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.
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 kinds of alcohols can be used to prepare ketones?
Secondary and tertiary alcohols can form ketones. A primary alcohol will form an aldehyde.
Is methyl octane alcohol alkane or alkenes?
Alcohol is an Oxygen atom double-bonded to a carbonyl group. As such, there is no such thing as 'Methyl Octane Alcohol'. However, there is Methyl Alcohol and Octyl Alcohol. Please edit your question. Also: If you are asking if Methyl Alcohol is miscible (dissoluble) in octane, it is. Alkanes are hydrocarbons only, so both octane and the methyl group in methanol (methyl alcohol) are alkanes.

What is used to supply some of the fuel needed by the brain only after the body has been fasting for a while?
Ketones
Which of the following is used to supply some of the fuel needed by the brain only after the body has been fasting for a while?
Ketones
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.
