How can you convert methyl benzene into benzene?
That is a very good question. But it is very hard to explain without the visualization of demonstration.
Convert benzene to methyl benzene by reacting it with CH3Cl and anhydrous AlCl3. Oxidize methyl benzene with a powerful oxidizing agent like alkaline KMnO4.
By the Friedel Crafts reaction of benzene with methyl chloride and anhydrous aluminium chloride.
Oxidation (with KMnO4) then decarboxylation (with soda lime) of ethyl benzene gives methyl benzene (Toluene) the repetition of same processes with mthylbenzene gives the benzene.
The molecular mass of the methyl benzene (toluene) is 92,1381.
The solubility difference between methyl alcohol (CH3OH) and benzene (C6H6) is related to the polar nature of methyl alcohol and the non polar nature of benzene. The OH group on methyl alcohol makes this a polar molecule and thus soluble in water. The lack of such a polar group in benzene makes it non polar, and thus insoluble in water.
Using Wurtz-Fittig reaction of chloro benzene with methyl chloride and sodium metal. However, it is likely that there will be ethane and biphenyl as byproducts.
Nope it isnt
because change happens
convert benzene to phenylacetylene
The formula is C7H8.
First Step: Friedel Craft Acylation on benzene to form phenyl methyl ketone or acetophenone. Second Step: Reduction of acetophenone by Clemmenen reduction using zinc amalgam and HCl to give the desired product. Another method is the reaction of benzene with ethyl chloride in presence of AlCl3 and heat in a close container.
since benzene has a very less boiling point , it will evaporate easily if the mixture is heated . Thus we can obtain the vapour and condense it to obtain solid benzene
toulene+sulphuric acid = o-methyl benzene sulphonic acid + p-methyl benzene sulphonic acid. Since methly group is ortho and para directed group so it activates benzene ring for electrophilic substitution reaction.
(C6H5CH2)+ is benzyl ion and C6H5CH3 is Toluene or Methyl benzene.
benzene with 2~chloropropane in presence of aluminiumchloride
Methylbenzene (toluene) is a cyclic hydrocarbon based on the benzene ring (C6H6) with a methyl group (CH3) replacing one of the hydrogens to give C7H8. The benzene ring itself is a rather special kind of hydrocarbon, but is considered to be unsaturated - Therefore, toluene is unsaturated. The saturated equivalent of benzene is cyclohexane (C6H12). The saturated equivalent of toluene is methylcyclohexane, C7H14.
Some additives I know of Ethyl methyl lead (octane booster and upper cylinder lube) Methyl Benzene (octane booster)
methyl increases the electron density of the benzene ring and so the electron densities of the ortho para positions are high. hence it directs the newly attaching groups to ortho and para positions....
firstly benzene with HNO3 and H2SO4 and you get nitrobenzene.
Benzene - a six carbon, six hydrogen [planar] ring - C6H6 - has no side-groups. Yet when any one single side-hydrogen is replaced with one Methyl (-CH3) Group, we have Toluene. Short Answer = one methyl group.
Diazotize with HCl and NaNO2 and then react with H3PO3. - - - - - Outside the educational environment you never convert aniline into benzene because there's no point - aniline is made from benzene and benzene is really, really cheap. So instead of going to the time and trouble of converting benzene into aniline then back to benzene, you just use the benzene the way it comes.
pH less than 7
convert methyl bromide into ethane
when phenol is treated with zinc dust it converts to benzene.....
benzene after oxidation convert into benzoic acid. zahra khan.
O-xylene is a benzene ring with two methyl groups in the ortho-positions. Methyl groups on a benzene ring act as o,p-directors, which means that they direct electrophiles to the carbon directly across or directly beside the existing methyl group. Friedel-crafts acylation creates the electrophile using a Lewis acid catalyst, however because there are two methyl groups side by side on o-xylene, the electrophilic addition is not as straightforward as described above. The two methyl groups… Read More
Oxidation via KMnO4. Benzene will not show positive results as it does not oxidize while methyl benzene shows positive results and oxidizes to benzolic acid (purple colour solution decolourizes)
I would like to know too
Israel Goldstein has written: 'Derivatives of 5-aceto carvacryl methyl ether' -- subject(s): Aceto carvacryl methyl ether, Benzene, Carvacrol
Convert the benzene into Phenol which is a good antiseptic material.
By Friedel crafts acylation, ie treating benzene with any CH3COX, where X is a halide.
You can find a detailed guide on how to Convert benzene to aspring on brynmawr.edu/chemistry/Chem/mnerzsto/synthesisofaspirin.htm
Tri-nitro toluene. Toluene is a benzene ring with a methyl group attached. The nitration of this to TNT occurs at the 2,4,6 positions.
Hi ,As you know from the structures of both the compounds that toluene has a methyl group on the benzene ring which is electron releasing group and hence activate the benzene ring by pushing the elctrons on the benzene ring. On the other hand nitro group on the benzene ring is electron withdrawing group which deactivates the benzene ring by withdrawing the electrons from the benzene ring . Now in the nitration attack of the… Read More
1. benzene to nitro benzene through nitration 2. nitro benzene to m-bromonitrobenzene by bromination 3. m-bromonitrobenzene to m-bromoaniline through halogenation in presence of Sn+HCl.
Oxidize the Toluene into Benzoic acid by using KMnO4 and then decarboxylation of benzoic acid with the help of Sodalime produces Benzene.
Cyclohexane can be converted into benzene by catalytic dehydrogenation in the presence of oxides of D block for ex V2O5, Cr2O3 etc. Cyclohexane when heated at 6000C in presence of Al2O3-Cr2O3 gives benzene.
Xylene is an aromatic hydrocarbon that consists of a benzene ring with two methyl substituents. It is nonpolar because there is an equal sharing of electrons between its atoms.
To synthesize acetophenone from benzene, you just need to add the aldehyde to the benzene ring. This can be done via a Friedel-Crafts acylation. The reagents are an acid chloride (acetyl chloride in this case) and AlCl3 (stoichiometric).
Methane + Chlorine = methyl chloride Methyl Chloride + Sodium + Propyl Chloride = Butane + Sodium Chloride (Wurtz Synthesis)
do a Friedel Crafts alkylation with ethyl halide and AlCl3.
blue litmus paper and red litmus paper does not change in color because it has no reaction occur.
The first step is a nitration: treat benzene with H2SO4 and HNO3. Then Sn and HCl under heat with a NaOH basic work-up will get you to aniline.
You nitrate the benzene with nitric and sulfuric acids, then catalytically hydrogenate the intermediate. But you're not going to do it at all if you can't raise the intermediate to 300 degrees C.
by removing 2 hydrogen atoms from C6H14(Hexane) to convert it into C6H12(Hexene;commonly called Bezene).
Methyl benzene, or toluene, does not have a lone pair of electrons and so cannot act as a base and take the hydrogen ion away from the HCl molecule.
in basic medium m-nitrobenzoic acid reacts with methanol to form methyl m-nitrobenzoate
pentane, hexane, benzene, kerosene, gasoline, some in acetone, methyl ethyl ketone, generally anything non polar with a low molecular weight
Benzene is a tidy, symmetrical molecule and packs very efficiently. The methyl group sticking out in methylbenzene tends to disrupt the closeness of the packing. If the molecules aren't as closely packed, the intermolecular forces don't work as well and so the melting point falls.
