Does phenol react with bromine?
Yes, at room temperature bromine reacts with phenol and forms 2,4,6-tribromo phenol.
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.
Chemical equation for the reaction of ethyne with bromine in carbon tetrachloride?
The question is not very specific, so there is more than just one answer, but I'm assuming you are referring to a radical bromination of an alkane (ethane) versus an electrophilic bromination of an alkene (ethene).Br2 in the presence of a radical initiator (such as light or heat) will add to ethane to form 2-bromoethane as the major product in a radical mechanism. This goes through an initiation step (forming 2 bromine radicals), followed by propagation to the alkane (forming a secondary ethyl radical), followed by a termination step. The termination step leading to the product is one where another bromine radical joins with the ethyl radical.In the absence of light or heat, bromine cannot react with an alkane, but it can react as an electrophile with an alkene. In this type of reaction (electrophilic addition to an alkene), the ∏-bond (double bond) on ethene attacks a bromine atom (from Br2) and kicks out a bromide (Br-). The bromine that was just added forms two bonds (one on each carbon of the double bond), giving a three-membered C-Br-C ring called a bromonium ion (since the bromine atom now has a positive charge). The bromide that left before can now attack the backside of the bromonium ion, opening the 3-membered ring, and adding anti to form a dibromoalkane (1,2-dibromoethane in this example). This reaction is stereospecific because in the major product the bromine atoms will always add anti (to the opposite side) on the alkene.
Forms when ozone and vehicle exhaust react with sunlight?
Smog
Who discovered plants react to sunlight understanding of photosynthesis is formed?
no
Why does polyethene not react in the same way with bromine water as ethene?
As polyehtene is unsaturated(single bond) it does not react with bromine and there is no colour change.But bromine reacts with ethene and it becomes colourless.
Does ethene react with Bromine in the presence of UV light?
Yes, however it doesn't require it either to react. ethene+bromine water→1,2-dibromoethane Ethane reacts with bromine only in the presence of UV forming bromoethane and hydrogen bromide.
Which tets coudl be used to distinguish between ethene and methane?
Ethene can react with Bromine water - turns colourless
Can methane and bromine react without sunlight?
Methane and bromine cannot react without the presence of sunlight or U.V light because of lack of energy which is usually supplied by the U.V light to break the bromine molecules to free radicals for the reaction to occur.Hope my answer helped.ABUAD
What decolorises bromine in the absence of sunlight?
Organic compounds called Alkenes turns Bromine to colourless from orange-ish without sunlight as a catalyst. Alkanes however require sunlight to react.
What test is used to show that ethene is unsaturated?
by adding bromine water to the compound. if it is unsaturated, the red colour of the bromine water will fade quickly. if it is saturated, then it will not fade.
How does the human body react to long periods without sunlight?
How does the human body react to long periods without sunlight?
Why does aluminum react with three bromine atoms?
When aluminum and bromine react, three bromine atoms combine with each aluminum atom.
Is bromine react able with air?
Bromine does not react with air because it is not possible. It is a non reactant element.
What is product of styrene react with bromine?
With bromine, it gives the dibromide.
Does silver react with bromine?
Yes, silver does react with bromine. Silver becomes oxidized in the presents of bromine gas, that's why silver jewelry tarnishes.
Does Bromine react with water?
no
