Which colour is having more refractive index?
Which color has best refractive index? The refractive index is maximum for violet colour. Can a medium have refractive index less than 1? Refractive index of a medium is always greater than 1 (it cannot be less than 1) because the speed of light in any medium is always less than that in a vacuum.

Which has higher refractive index?
The chemistry and the absorption bands of the materials are important to making a good prediction about refractive index. For example, semiconductors like silicon, germanium, and diamond tend to have very high indices. But everything else held constant, the partial derivative of of the refractive index with respect to density is positive.
What is the formula of refractive index?
The refractive index is related to the molar refractivity, structure and weight of the monomer. What is the formula for refractive index? Formula 3 – Refractive Index (or Index of Refraction) n = c/η.
What is the formula of cyclohexene?
C6H10Cyclohexene / FormulaCyclohexene is a hydrocarbon with the formula C6H10. This cycloalkene is a colorless liquid with a sharp smell. It is an intermediate in various industrial processes. Cyclohexene is not very stable upon long term storage with exposure to light and air because it forms peroxides.
What does cyclohexene look like?
Cyclohexene appears as a colorless liquid. Insoluble in water and less dense than water. Flash point 20°F. Vapors heavier than air.
Is cyclohexene an alkene?
Cyclohexene is a typical alkene, and benzene and anisole are aromatic compounds. The methoxy substituent present in anisole increases the nucleophilicity of the aromatic ring, and greatly enhances the reactivity of the ring toward electrophilic attack.
What functional group is in cyclohexene?
alkene functional groupCyclohexene is a clear organic liquid compound with six carbons and ten hydrogens - C6H10 C 6 H 10 . The structure is a ring (cyclo) of six (hex) carbons with one double bond (-ene) and hydrogen coming off of the ring. It is a member of the alkene functional group.
What is the common name of cyclohexene?
CyclohexeneNamesPreferred IUPAC name CyclohexeneOther names Tetrahydrobenzene, 1,2,3,4-Tetrahydrobenzene, Benzenetetrahydride, Cyclohex-1-ene, Hexanaphthylene, UN 2256IdentifiersCAS Number110-83-849 more rows
What is the bond angle of cyclohexene?
109.5 degreesCarbon atoms like to form bond angles of 109.5 degrees. This bond angle keeps the carbon atoms as close as possible without them interfering with each other. But if cyclohexane were in a flat hexagon, the bond angle would be 120 degrees.
Is cyclohexene polar or nonpolar?
As such, in the "battle for electrons" waged by the atoms, it is a "draw." The carbon and hydrogen atoms enter the relationship neutral, and remain relatively neutral after forming covalent bonds that define the structure of the cyclohexane molecule. That makes cyclohexane nonpolar.
Is cyclohexene saturated or unsaturated?
Unsaturated: A molecule having one or more pi bonds. Often refers to carbon-carbon pi bonds, but can include other pi bonds as well. Cyclohexene has a pi bond; it is unsaturated.
Why is cyclohexene used for?
Cyclohexene is a clear, colorless liquid with a sweet odor. It is used in oil extraction, to make other chemicals, and as a catalyst solvent. It is also found as a component of motor vehicle exhaust.
What Colour is cyclohexane?
Cyclohexane appears as a clear colorless liquid with a petroleum-like odor. Used to make nylon, as a solvent, paint remover, and to make other chemicals.
Why is cyclohexene washed with water?
Washing with water removes most of the impurities. Treatment with sodium carbonate solution removes traces of acid and a final wash with water removes any remaining carbonate. The mechanism of the dehydration of cyclohexanol probably involves the formation of a carbocation.
Is cyclohexene an acid or a base?
The reaction between cyclohexene and HCl can be treated as a Lewis acid-base interaction. HCl acts as the Lewis acid, and cyclohexene, having a π bond, is the Lewis base.
How can you distinguish between benzene and cyclohexene?
Cyclohexene has strong aliphatic C-H stretching absorptions at 3000-2850 cm⁻¹ whereas Benzene does not. So, IR spectroscopy can be used to distinguish between Benzene and Cyclohexane as cyclohexane will give a positive result and benzene does not.
How will you distinguish between cyclohexane and cyclohexene?
Cyclohexane is a cyclic alkane compound while cyclohexene is a cyclic alkene compound. The key difference between cyclohexane and cyclohexene is that the cyclohexane is a saturated hydrocarbon whereas the cyclohexene is an unsaturated hydrocarbon.
What is cyclohexene used for?
Cyclohexene is a clear, colorless liquid with a sweet odor. It is used in oil extraction, to make other chemicals, and as a catalyst solvent. It is also found as a component of motor vehicle exhaust.
Where is cyclohexene found?
Cyclohexene is found in the form of vapors in the environment and released as waste streams from the manufacturing units. Cyclohexene exposure is expected through inhalation and dermal contact in the workplace where cyclohexene is either produced or employed as an intermediate chemical.
Is cyclohexene a chemical compound?
Chemical compound. Cyclohexene is a hydrocarbon with the formula C 6 H 10. This cycloalkene is a colorless liquid with a sharp smell. It is an intermediate in various industrial processes. Cyclohexene is not very stable upon long term storage with exposure to light and air because it forms peroxides .
Is cyclohexene a half chair?
Cyclohexene is most stable in a half-chair conformation, unlike the preference for a chair form of cyclohexane. One basis for the cyclohexane conformational preference for a chair is that it allows each bond of the ring to adopt a staggered conformation. For cyclohexene, however, the alkene is planar, equivalent to an eclipsed conformation at that bond.
Overview
Cyclohexene is a hydrocarbon with the formula C6H10. This cycloalkene is a colorless liquid with a sharp smell. It is an intermediate in various industrial processes. Cyclohexene is not very stable upon long term storage with exposure to light and air because it forms peroxides.
Production and uses
Cyclohexene is produced by the partial hydrogenation of benzene, a process developed by the Asahi Chemical company. In the laboratory, it can be prepared by dehydration of cyclohexanol.
Reactions and uses
Benzene is converted to cyclohexylbenzene by acid-catalyzed alkylation with cyclohexene. Cyclohexylbenzene is a precursor to both phenol and cyclohexanone.
Hydration of cyclohexene gives cyclohexanol, which can be dehydrogenated to give cyclohexanone, a precursor to caprolactam.
The oxidative cleavage of cyclohexene gives adipic acid. Hydrogen peroxide is used as the oxidan…
