Principle in seliwanoff's test?
dehydrated ketones react with resorcinol to give a deep cheery red colour and aldose react to give a faint pink colour.
Why does alkene reacts kmno4?
KMnO4 will react with compounds having unsaturation (double bond or triple bond). Since alkenes have double bond, it will react with KMnO4 and decolourize dilute KMnO4 solution.
What is the function of Fehling's test?
Fehling's test is used to differentiate between aldehyde and ketones group. An aldehyde group will react with Fehling's reagent to give cuprous oxide resulting in a red precipitate. A Ketone group will not react with Fehling's reagent.
What is the reaction between alcoholic KOH and alkyl halide?
When alc. KOH react with alkyle halide it for Alkene, KX (X Is stande for halide) and water. And this reaction also called Dehydrohalogenation...
What is the reaction between hydrocarbons and sodium hydroxide?
A hydrocarbon such as an alkane, alkene, or alkyne will NOT react with a hydroxide ion. Simply put, the base is not strong enough to deprotonate these molecules. The resulting anion would Not form,,,,,since a stronger base would be generated. For example, if methane was deprotonated,,,,,we would get the methide anion......This is MUCH MUCH stronger than the OH- ion........a reaction is not favorable when a stronger base is generated. The same logic applies to generation of a base from the alkene or alkyne.
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!

Why does alkene reacts kmno4?
KMnO4 will react with compounds having unsaturation (double bond or triple bond). Since alkenes have double bond, it will react with KMnO4 and decolourize dilute KMnO4 solution.
Can ketones be formed from fatty acids?
ketone bodies formed when amount of acetyl-CoA produced is excessive compared to the amount of oxaloacetateavailable to react with it.
When preforming the bromine test to distinguish between aromatic and alkene compound?
An alkane will react with the bromine test and become a clear/colourless liquid, while an aromatic hydrocarbon will not react with the bromine and remain a redish-orange tinged liquid.
What is the function of Fehling's test?
Fehling's test is used to differentiate between aldehyde and ketones group. An aldehyde group will react with Fehling's reagent to give cuprous oxide resulting in a red precipitate. A Ketone group will not react with Fehling's reagent.
Does methane reacts with chlorine in dark?
Theotically, methane can't react with Cl2 in shade as UV light is required to initiate the substitution reaction. Only when there is Cl2 can the C-H bond be broken. However, alkene can react directly with Cl2 due to hydrohalogenation.

what is the outcome of tollens reagent reacting with methanal, ethanol and propanone?
The outcome of the Tollens reagent reacting with methanal (formaldehyde), ethanol (ethyl alcohol), and propanone (acetone) is the formation of metallic silver (Ag) in the case of methanal, while ethanol and propanone do not show a significant reaction with Tollens reagent. Tollens reagent is used as a chemical test to distinguish between aldehydes and ketones, where aldehydes react to produce a silver mirror, while ketones do not react.
What is the reaction between alkene and bayer reagent?
well this reaction its a test for distinction of unsaturated hydrocarbons from saturated ones.and when unsaturated hydrocarbons react with baeyer's reagent its pink colour disappears. What happens in this reaction is actually the KMnO4 reacts with alkali and releases K2MnO4+H2O+[O] The nascent oxygen along with water reacts with alkene giving off alkanediol.
What simple chemical test will distinguish an alkane from others?
Use bromine water (Br2) or acidified permanganate (H+/MnO4-) With permanganate: add the permanganate to the alkane and no reaction will occur, add the permanganate to the alkene and you will form a diol the solution will also turn from purple to colourless. With bromine water: add the bromine water to the alkane (plus you need sunlight) and you get a substitution reaction, this is a slow reaction. Add the bromine water to the alkene and you get an immediate addition reaction (this one does not need sunlight). When bromine water reacts with an alkene it is decolourised, the reddish brown bromine water turns from brown to colourless. This is because alkenes are unsaturated and contain a carbon to carbon double bond. If you did the bromine water test in a dark place say a cupboard then the alkene would decolourise but the alkane wouldn't because it needs UV/sunlight in order to react. in practice the cupboard is not necessary as the speed of decolourisation is so much faster with the alkene.
Why alkene gives more soot than alkane?
Comparing ethane and ethene . there proportionally more hydrogens in ethane. Conversely there are proportionally more carbons in ethene. Ethane C:H:: 1:3 or 1/3 : 1 Ethene C:H :: 1:2 or 1/2 : 1 Since the fraction '1/2' > 1/3' then more carbon (soot).
