Cyclohexane has no pi-unsaturation and is therefore not nucleophilic. It does not react with bromine unless energy in the form of light or heat is applied. In such a case a free-radical substitution reaction occurs. Cyclohexene is a typical alkene, and benzene and anisole are aromatic compounds.

Does cyclohexane undergo bromination?
Cyclohexane has no pi-unsaturation and is therefore not nucleophilic. It does not react with bromine unless energy in the form of light or heat is applied. In such a case a free-radical substitution reaction occurs. Cyclohexene is a typical alkene, and benzene and anisole are aromatic compounds.
What is bromination with example?
The bromination of benzene is an example of an electrophilic aromatic substitution reaction. In this reaction, the electrophile (bromine) forms a sigma bond to the benzene ring, yielding an intermediate. Then, a proton is removed from the intermediate to form a substituted benzene ring.
Why does cyclohexane not react with kmno4?
Cyclohexane does not react. The secondary alcohol cyclohexanol is oxidized by permanganate to give the ketone cyclohexanone. The alkene cyclohexene reacts to give cis-1,2-cyclohenanediol. The permanganate ion is reduced to the green manganate ion.
What do you expect when cyclohexane reacts with one mole of bromine in presence of UV light?
UV light splits bromine molecules into highly reactive Br radicals. These attack the hydrogens on the cyclohexane, and react, to form (colorless) bromocyclohexane (I think) and (also colorless) hydrobromic acid. So the brown bromine forms colorless compounds, which makes it appear to discolor.
How does cyclohexane react with bromine water?
Cyclohexane will react slowly with bromine water, and no decolourisation of bromine water will occur. Cyclohexene will react quickly and spontaneously with bromine water, and bromine water will be decolourised from brown to colourless.
Why does cyclohexane react with bromine water?
This means that Cyclohexene is able to induce a tempoary dipole in Br-Br molecules and this allows one Br to attract an electron pair from the double bond, leading to bromination of the cyclohexene into 1,2-bromocyclohexane.
Why does cyclohexane not react with bromine?
Cyclohexane has no pi-unsaturation and is therefore not nucleophilic. It does not react with bromine unless energy in the form of light or heat is applied. In such a case a free-radical substitution reaction occurs.
What happens when methylcyclohexane reacts with molecular bromine?
“Methylcyclohexane reacts with molecular bromine (Br2) in the presence of light and heat. The major product obtained from this reaction is reacted with sodium ethoxide in ethanol at 55°C. Draw the skeletal structure of the major organic product resulting from the second reaction.”.
What is the NBS bromination of cyclohexene?
NBS Brominationof Cyclohexene Relevant textbook readings– Klein, Chapter 11 Overview – Cyclohexene will be reacted with N-bromosuccinimide(NBS) to form 3-bromocyclohexene.
What does methylcyclohexane look like?
Methylcyclohexane appears as a clear colorless liquid with a petroleum-like odor. Flash point 25°F. Less dense than water and insoluble in water. Vapors heavier than air. Methylcyclohexane is a cycloalkane that is cyclohexane substituted by a single methyl group. It has a role as an aprotic solvent, a plant metabolite and a human metabolite.
How is methylcyclohexane produced?
Methylcyclohexane is produced, as an intermediate or a final product, by process units covered under this subpart. The substance can be absorbed into the body by inhalation of its vapour and by ingestion.
