?一：isomers是什么意思（中英文）解釋的意思

isomers是指具有相同分子式但結(jié)構(gòu)不同的化合物。它們擁有相同的原子組成和相同的分子量，但它們的原子排列方式不同，因此具有不同的物理和化學(xué)性質(zhì)。

Isomers is a term used to describe compounds that have the same molecular formula but different structures. They have the same atomic composition and molecular weight, but their arrangement of atoms is different, resulting in different physical and chemical properties.

二：怎么讀（音標(biāo)）

Isomers [?a?s?m?rz]

三：用法

Isomers通常用于有機化學(xué)和生物化學(xué)領(lǐng)域，用來描述具有相同分子式但結(jié)構(gòu)不同的化合物。它們可以通過改變原子之間的連接方式或改變它們所處的空間位置來產(chǎn)生。在化學(xué)反應(yīng)中，isomers可能會表現(xiàn)出不同的反應(yīng)性能，因此對于研究和制備特定化合物非常重要。

Isomers are commonly used in organic chemistry and biochemistry to describe compounds with the same molecular formula but different structures. They can be produced by changing the way atoms are connected or by altering their spatial positions. In chemical reactions, isomers may exhibit different reactivity, making them important for studying and synthesizing specific compounds.

四：例句1-5句且中英對照

1. These two compounds are isomers, with the same molecular formula but different arrangements of atoms.

這兩種化合物是同分異構(gòu)體，具有相同的分子式但原子排列不同。

2. Isomers can have vastly different properties, such as melting point, boiling point, and reactivity.

同分異構(gòu)體可以具有完全不同的性質(zhì)，如熔點、沸點和反應(yīng)性。

3. In organic chemistry, the study of isomers plays a crucial role in understanding the structure and function of molecules.

在有機化學(xué)中，研究同分異構(gòu)體對于理解分子的結(jié)構(gòu)和功能起著至關(guān)重要的作用。

4. The two isomers of butane, n-butane and isobutane, have different physical properties due to their different structures.

丁烷的兩種同分異構(gòu)體，正丁烷和異丁烷，由于結(jié)構(gòu)不同而具有不同的物理性質(zhì)。

5. Isomerism is a common phenomenon in nature, as many biological molecules exist as isomers with distinct functions.

同分異構(gòu)現(xiàn)象是自然界中常見的現(xiàn)象，許多生物分子都存在著具有不同功能的同分異構(gòu)體。

五：同義詞及用法

1. Stereoisomers - refers to isomers that have the same molecular formula and connectivity but differ in the three-dimensional arrangement of atoms.

2. Structural isomers - describes compounds with the same molecular formula but different bonding patterns between atoms.

3. Geometric isomers - used to describe compounds with restricted rotation around a double bond or ring structure, resulting in different spatial arrangements.

4. Optical isomers - also known as enantiomers, they are mirror images of each other and cannot be superimposed, often exhibiting different biological activities.

六：編輯總結(jié)

Isomers是指具有相同分子式但結(jié)構(gòu)不同的化合物，它們在化學(xué)性質(zhì)和物理性質(zhì)上可能存在差異。在有機化學(xué)和生物化學(xué)領(lǐng)域，研究和了解isomers對于理解分子的結(jié)構(gòu)和功能非常重要。同義詞包括stereoisomers、structural isomers、geometric isomers和optical isomers。通過改變原子之間的連接方式或改變它們所處的空間位置，可以產(chǎn)生不同類型的isomers。
