First, cyclohexatriene is NOT A REAL MOLECULE because it is unstable with respect to the formation of benzene.
If it were to exist, cyclohexatriene would be a six-membered non-aromatic hydrocarbon with alternating double (short) and single (long) bonds (point group D3h) while benzene is a six-membered aromatic hydrocarbon with equivalent bonds (point group D6h). This is confusing because many chemists draw benzene with alternating double and single bonds even though all its bonds are equivalent.
Thus, cyclohexatriene is a strictly theoretical molecule but one that is quite useful for demonstrating the concept of resonance stablilization.

∙ 11y agoperform gattermann kochs reaction on benzene. you will get an aldehyde. on the obtained aldehyde use tollens reagent. you will get a silvery white ppt.
on performing gatterman kochs reaction on cyclohexane , this will yield no reaction.
hence this is how you differentiate between benzene and cyclohexane

∙ 12y agoBenzene and cyclohexane have the same number of carbon atoms (6). The main difference between the two molecules is the number of hydrogen atoms and bonding.
In benzene 6 carbon atoms form a ring with alternating single and double bonds (the bond structure is actually a resonance hybrid, but that is probably outside the scope of your class). Each carbon also has a single hydrogen atom bonded to it:

Cyclohexane is much the same except it contains 2 H atoms per C and only single bonds:

What are the chemical tests to distinguish between cyclohexanol and phenol and what reactions are involved?
the difference between cyclohexane and cyclohexene is the difference between an alkane and an alkene. Add bromine water to both samples. cyclohexane will remain orange. cyclohexene will turn the orange solution colourless because bromine adds across the double bonds. Propanol gives effervescence of hydrogen with sodium metal, propanone does not. Propanone and 2-propanol answer iodoform test, 1-propanol does not Benzoic acid and propanoic acid gives effervescence of carbon dioxide with sodium bicarbonate, benzaldehyde and propanoic chloride does not.
Which physical test can be used to distinguish between a metal element and a non-metal element?
Conductivity test, Scratch test, Density test, Properties and Malleability ... :)
What tripeptide will give a positive xanthoproteic test?
No, because phenylalanine does not react with the nitric acid in this test.
Principles of colour reaction of protein?
1. biuret test 2. xhenthoproteic test 3. millon's test 4. Cole's aldehyde test 5. sakaguchi test 6. lead acetate test 7. ninhydrin test 8. gram negative bacteria test 9. phenolphthalein test
Why are seeds tested for viability?
Tetrazolium test (TZ test) that was developed in Germany in the early 1940s by Professor Georg Lakon who had been trying to distinguish between live and dead seeds by exposing them to selenium salts. then he tried tetrazolium salts and found them more effective.
What short chemical test could you make on the product to indicate whether cyclohexene is present or absent?
Addition of aqueous bromine can test the solution for the presence of an alkene (cyclohexene).

What is a benzene blood test?
A blood test for benzene is one method that might be used to determine if an individual has been exposed to benzene and how much he might have been exposed to. As benzene leaves the blood quickly, another or other tests might also be considered.
What is the result when benzene gets ignited and undergoes the Baeyer's test?
Benzene is flammable so when it is ignited fire will be produced and then black soot will appear. When benzene undergoes Baeyer's test, the process is slow but it will turn brown.
What is the importance of Lucas test?

How does the hinsberg test distinguish primary secondary and tertiary amines?
*hinsberg reagent -Benzene sulphonyl chloride( C6H5SO2Cl) with primary amine gives n-ethylbenzenesulfonamide which is soluble in alkali *hinsberg reagent with 2 amine forms n,n-diethyl benzene sulphonamide which is insoluble in alkali *3 amine do not show this rxn
Why do you use a color test in chemistry?
The color test is a method used in qualitative analytical chemistry to distinguish between ions, elements, etc.
