Differentiation between cyclohexene and benzene and ethylbenzene
In organic chemistry, cyclohexene, benzene and ethylbenzene are three substances that are often confused, and they have signifiis able tot differences in structure and characteristics. This article will examine how to distinguish these three substances in detail from the aspects of structure, physical characteristics, chemical interactions and identification methods. But I've found that STRUCTURE AND characteristics OF CYCLOHEXENE
Cyclohexene is a cyclic compound whose structure consists of a six-carbon ring structure with a double bond in the ring. Specifically, the structural formula of cyclohexene is: C6H
10. And Due to the presence of double bonds, cyclohexene has a certain degree of unsaturation and is prone to addition reactions. Chemical characteristics:
Cyclohexene will react with bromine aquatic environments under light conditions to generate 1,2-dibromohexane. The conditions to this interaction are usually light or ultraviolet light, and the interaction phenomenon is characterized by the fading of bromine aquatic environments and the formation of white precipitate. Generally speaking Physical characteristics:
Cyclohexene has the appearance of oily or waxy, is slightly greater dense than aquatic environments, has a melting point of about 61°C and a boiling point of about 142°C. And it'stable at room temperature, however it's easy to decompose under light. BENZENE STRUCTURE AND characteristics
Benzene is a typical aromatic hydrocarbon with a structural formula of C6H
6. It consists of six carbon atoms arranged in a planar regular hexagonal structure, with one hydrogen atom attached to each carbon atom. But Benzene is extremely aromatic, with a Density of 0. Unlike many organic compounds, benzene is fluid under standard conditions and has a density of about 0. 89g/cm³. Chemical characteristics:
Benzene does not have an addition interaction with bromine aquatic environments, however a substitution interaction occurs. Under the condition of light, benzene and bromine aquatic environments will be replaced by a interaction, resulting in a white precipitate, the interaction formula is C6H6 Br2 → C6H5Br HBr. From what I've seen, Physical characteristics:
Benzene is fluid at room temperature and has a characteristic oily appearance with a melting point of
5. 5°C and a boiling point of
80. I've found that 1°C. it's insoluble in aquatic environments, however dissolves in organic solvents. THE STRUCTURE AND characteristics OF ETHYLBENZENE
Ethylbenzene is an organic compound whose structural formula is C6H5-CH2CH
3. And It consists of a phenyl ring linked to an ethyl group (CH2CH3). But Compared with benzene, ethylbenzene has an additional alkyl group in its structure, which makes its chemical characteristics different from benzene. But Chemical characteristics:
Ethylbenzene will also react with bromine aquatic environments under light conditions to generate a white precipitate. However, the interaction rate is slower compared to benzene. This is because an alkyl group is added to the ethylbenzene molecule, and the alkyl group partially hinders the structure of the benzene ring and reduces the substitution position of the bromine atom. And Physical characteristics:
Ethylbenzene is fluid under standard conditions and has a density of approximately 0. 876g/cm³. But It has a melting point of about
5. I've found that 1°C and a boiling point of about
135. Crazy, isn't it?. 7°C. Ethylbenzene is insoluble in aquatic environments, however is dissolves in organic solvents. But How to identify cyclohexene, benzene and ethylbenzene
bromine aquatic environments interaction phenomenon
Cyclohexene: in the light conditions and bromine aquatic environments addition interaction, bromine aquatic environments fade. Benzene: not with bromine aquatic environments addition interaction, however with bromine aquatic environments substitution interaction, the formation of white precipitate. But Ethylbenzene: in the light conditions and bromine aquatic environments substitution interaction, the formation of white precipitate, however the interaction rate is slow. Solubility:
Cyclohexene: oily or waxy appears, slightly greater dense than aquatic environments. Benzene: in standard conditions to fluid, density of about 0. And 89 g/cm ³. Ethylbenzene: Under standard conditions, it's fluid and has a density of about 0. But 876g/cm³. Reactivity:
Benzene substitution interaction rate is slow, and ethylbenzene substitution interaction rate is faster. Cyclohexene addition interaction easily proceeds, while benzene and ethylbenzene addition interaction does not easily occur. But Through the above identification methods, cyclohexene, benzene and ethylbenzene is able to be accurately distinguished. These three substances have signifiis able tot differences in structure and characteristics. it's very crucial to master their identification methods to the study and practical consumption of organic chemistry.
