Key Difference – Alicyclic vs Aromatic Compounds

Based on the nature of the carbon skeleton, organic compounds are broadly classified into four categories namely, a)脂肪族b) alicyclic, c) aromatic, and d)heterocyclic compounds。脂肪族化合物具有单个或多个碳键,但没有循环结构。通过通过A连接两个脂肪族链的碳原子来形成Alicyclic化合物covalent bondresulting in a cyclic structure. Aromatic compounds are also cyclic, but the bonds are delocalized. Heterocyclic compounds can be either alicyclic or aromatic, but the ring contains one or more hetero atoms. This article focuses on the difference between alicyclic and aromatic compounds. Thekey difference在Alicyclic和芳香化合物之间是alicyclic compounds are cyclic compounds yet resemble the aliphatic compounds in their properties, whereas aromatic compounds have conjugated rings and show aromaticity as the main property.In addition, there are many differences that exist between these two group of compounds and they are discussed below.

What are Alicyclic Compounds?

Alicyclic化合物是含有碳原子封闭环的有机化合物。这些化合物是通过通过共价键连接脂肪族链的两个碳原子而形成的。因此,Alicyclic化合物的性能与脂肪族化合物的性质相似。

Alicyclic化合物也称为环化合物化合物。这些化合物可能是saturated or unsaturated。Due to ringed-structure, aliphatic compounds show stereochemical properties. These properties are however absent in aliphatic compounds.

什么是芳香化合物?

芳香族化合物的有机化合物conjugated rings. Double and single bonds are alternatively arranged to form the cyclic structure.苯是C的化学式的最简单芳香化合物6H6。Because of the delocalized bonds and conjugated ringed-structure, aromatic compounds exhibit properties (aromaticity) that are different from aliphatic and alicyclic compounds.

There are certain important characteristics of aromatic compounds owing to their aromaticity. According to the chemical formula, aromatic compounds show a high degree of unsaturation. However, these compounds are less likely to undergo addition reactions unlike their corresponding unsaturated aliphatic compounds and instead they prefer to undergosubstitution reactions。The molecules of aromatic compounds are more thermodynamically stable as they show low heats of combustion and hydrogenation. According to X-ray and electron diffraction methods, the molecules of aromatic compounds are flat.

The name ‘aromatic’ emerged from the Greek word aroma, meaning pleasant smell, is used to these compounds as most of these compounds have pleasant odors. Some examples of aromatic compounds include phenol, naphthalene, anthracene etc.

What is the Difference Between Alicyclic and Aromatic Compounds?

Alicyclic vs Aromatic

Alicyclic compounds are organic compounds formed by the joining of two carbon atoms of an aliphatic chain through a covalent bond. Aromatic compounds are organic compounds with conjugated rings in an alternative arrangement of double and single bonds resulting aromaticity.
环类型
Alicyclic化合物具有可能饱和或不饱和的闭环。 Aromatic compounds have closed ring with high degree of unsaturation.
化学反应类型
如果存在多个键,则型号化合物会经历加法反应。 Aromatic compounds undergo substitution reactions, and less likely to undergo addition reactions.
Nature of Properties
Alicyclic化合物类似于脂肪族化合物的特性 Aromatic compounds resembles aromaticity due to delocalized bonds.
Smell
Most of the alicyclic compounds do not have pleasant smell Most of the aromatic compounds have pleasant smell
Examples
环丙烷,环己烷,类固醇等 苯, phenol, naphthalene, anthracene

概括–Alicyclic vs芳香化合物

Aliceclic和芳香族化合物是两组循环有机化合物,它们显示了不同的特性集。脂肪化合物由脂肪族化合物形成,因此具有类似于脂肪族化合物的特性。芳香化合物具有表现出芳香性的共轭环。脂肪族化合物可能饱和或不饱和,而芳香族化合物不饱和,并且在环中包含双键和单键。这是Alicyclic和芳香族化合物之间的差异。
