常见错误

❌ 错误:This is a heterocyclic.
✓ 正确:This is a heterocyclic compound.

heterocyclic 是形容词,不能单独作名词使用,需要修饰名词如 compound 或 ring。

✓ 正确:The molecule has a heterocyclic structure.

heterocyclic 作为形容词,必须后接名词来描述具体特征,不能单独使用。

近义词辨析

cyclic

cyclic 泛指任何环状结构,而 heterocyclic 特指环中含有不同原子(如氮、氧、硫)的化合物,更具体。

Cyclic compounds include both homocyclic (e.g., benzene) and heterocyclic (e.g., pyridine) types.

aromatic

aromatic 强调环状结构的芳香性(如苯环),而 heterocyclic 强调环中原子种类的多样性,两者可能重叠但不完全相同。

Pyridine is both aromatic and heterocyclic, containing a nitrogen atom in its ring.
