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.
One way to distinguish between benzene and cyclohexene is through a bromine water test. Cyclohexene will react with bromine water, turning it from orange/red to colorless due to the addition reaction with the double bond in cyclohexene. Benzene, being a stable aromatic compound, will not react with bromine water and the orange/red color will remain.
perform 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
Benzene 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?
One physical test that can be used to distinguish between a metal element and a non-metal element is the ability to conduct electricity. Metals generally conduct electricity well, whereas non-metals are poor conductors. Another test is the luster or appearance - metals are usually shiny and have a metallic luster, while non-metals are dull in appearance.
What tripeptide will give a positive xanthoproteic test?
Phenylalanine. When phenylalanine is subjected to a xanthoproteic test, it will produce a yellow solution due to the reaction of the aromatic ring with nitric acid, indicating the presence of phenyl group in the tripeptide.
What properties could not be used to distinguish between table salt and table sugar?
color
If you have isolated a gram-positive coccus from a throat culture that you cannot identify as staphlycocci or streptococci A test for one enzyme can be used to distinguish quickly between these bacter?
The catalase test can be used to distinguish quickly between Staphylococci and Streptococci in a gram-positive coccus isolated from a throat culture. Staphylococci are catalase positive (produce bubbles with hydrogen peroxide), while Streptococci are catalase negative (no bubble formation). This test can help differentiate between these two bacterial groups based on their enzyme activity.
What is a simple chemical test to distinguish between bezene and hexane answer?
One simple chemical test to distinguish between benzene and hexane is the Bromine test. Benzene will not react with bromine in the absence of a catalyst, while hexane will readily react with bromine to form a colorless product.
What short chemical test could you make on the product to indicate whether cyclohexene is present or absent?
One simple test to determine the presence of cyclohexene would be to perform a bromine water test. Add a few drops of bromine water to the product; if cyclohexene is present, the red-brown color of the bromine water will disappear due to addition reaction with the cyclohexene. If the color remains, it indicates that cyclohexene is absent.
What is the distinguishing test between primay secondary and tertiary amine?
The distinguishing test between primary, secondary, and tertiary amines is the Hinsberg test. In this test, the amine is reacted with benzene sulfonyl chloride. Primary amines produce insoluble precipitates, secondary amines form soluble products, and tertiary amines do not react.

What is a benzene blood test?
A benzene blood test measures the levels of benzene, which is a toxic chemical found in the environment and some industrial products. High levels of benzene in the blood can lead to health issues such as anemia, leukemia, and other blood disorders. The test is typically used to assess exposure to benzene in occupational settings or environmental contamination.
What result would benzene have in ferrox test?
In the ferrox test, benzene would not show any result because benzene is not reactive with the reagents used in the test. The ferrox test is typically used to detect the presence of phenol or compounds with a phenolic group, which can form colored complexes with the reagents. Benzene lacks this functional group and therefore does not participate in the reaction.
What test that would be able to distinguish between glucose and ribose?
Benedict's test can distinguish between glucose and ribose. Glucose will give a positive result by forming a colored precipitate, while ribose will not react with Benedict's reagent, remaining clear blue.
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 chemical test will distinguish chlorine salt from sulfate salt?
A waft test may help in distinguishing between the salts only by their smell.
Can a urine test distinguish between different benzodiazepines?
I went for a drug screen and when my results came in, my doctor could tell that I had taken Xanex, Klonapin, and Ativan. So yes, they can distinguish between the different benzos!
Different between TB and pneumonia in X-ray?
They are both scarring but you cannot distinguish between them through a mere XRAY. You have to have a Tb skin test done or a sputum culture test
