Any number of chemical moieties could react with alkanes to produce new compounds in a substitution reaction.
For example, hydrohalic acids (HCl, HBr, HI) could react with an alkane to produce a haloalkane. Here, the halogen atom would replace one of the hydrogen atoms in the alkane.
(HCl + ethane --> chloroethane)
(HBr + propane --> bromopropane)
This also works with other reactive species, such as:
- nitric acid + alkane --> nitroalkane

How iodine reacts with lipid molecules?
Displaces hydrogen molecules in a substitution reaction. (which means your skin turns purple)
What changes in color occur when bromine or KMnO4 reacts with an alkane?
Purple to colourless
What is wolfkrishner reduction reaction?
Wolff-Kishner reaction is used in order to reduce a ketone to an alkane. NH2NH2 (hydrozine) and KOH are used in the reaction.
What are substitution reactions of Alkane?
Yes, it can be converted thermally or photochemically by dehydrogenation using iridium complexes as catalysts.
What alkane is fire?
Fire is not an alkane or any substance in particular. Fire is a reaction between a flammable substance and an oxygen. All alkanes are flammable, but there are other flammable substances as well.

When an alkane reacts with Br2 what does it produce?
A bromoalkane may be obtained.
Is an alkene to an alkane a oxidation reaction?
no
What changes in color occur when bromine or KMnO4 reacts with an alkane?
Purple to colourless
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.
What reaction does aromatics undergo?
Substitution
What happens when a reaction take place between an alkene and alkane?
If alkene is straight chain and alkane has one tertiary carbon atom then alkylation of alkene takes place and a substituted alkane is produced.
WHY DID THE IRON ROD KEPT IN COPPER SULPHATE SOLUTION TURNED BROWN AFTER SOMETIME?
The Iron rod(Fe) reacts with the Copper Sulphate. Substitution reaction takes place. Fe+CuSO4--> FeSO4 + Cu
What are substitution reactions of Alkane?
Yes, it can be converted thermally or photochemically by dehydrogenation using iridium complexes as catalysts.
Discuss the SN reaction with example?
The SN reaction is a substitution reaction. An example of the SN reaction is Br. H3CH2C.
What is wolfkrishner reduction reaction?
Wolff-Kishner reaction is used in order to reduce a ketone to an alkane. NH2NH2 (hydrozine) and KOH are used in the reaction.
Is esterfication a substitution or addition reaction?
It is substitution because hydrogen of carboxylic acid is replaced by an alkyl group.
