trung phân
Definition
- Noun (Chemistry):
- Mesomer: A state or concept in chemistry describing a molecule that cannot be accurately represented by a single structural formula but is instead a hybrid of several possible structures. These structures differ only in the distribution of electrons, not in the positions of atoms.
- Resonance hybrid: A molecule for which two or more valid Lewis structures (resonance forms) can be drawn to represent its bonding. The actual molecule is an average of these forms.
Usage Examples
- Noun:
- Benzene là một ví dụ điển hình của hiện tượng trung phân. (Benzene is a classic example of mesomerism.)
- Cấu trúc trung phân giúp giải thích tính ổn định của phân tử. (The resonance hybrid structure helps explain the stability of the molecule.)
Advanced Usage
- "Hiện tượng trung phân": The phenomenon of resonance or mesomerism in chemistry.
- Hiện tượng trung phân rất quan trọng trong hóa học hữu cơ. (The phenomenon of resonance is very important in organic chemistry.)
Variants and Related Words
Cộng hưởng (n): Resonance. This is a more common synonym in modern Vietnamese chemistry terminology.
- Cấu trúc cộng hưởng (Resonance structure)
Dạng trung gian (n): Intermediate form (can be used in a broader chemical context).
Synonyms
- Resonance hybrid
- Mesomeric structure
- Resonance structure (refers to the individual contributing forms, not the hybrid itself)
Notes on Usage
- "Trung phân" is a specialized scientific term. In contemporary Vietnamese, "cộng hưởng" is more frequently used to describe the same chemical concept.
- The term is primarily used as a noun and is not commonly used in everyday language outside of chemistry.
