什麼是 Chemical Name Generator？
This chemical name generator (a chemical compound name generator) converts between chemical formulas and names in both directions. Enter H2SO4 to get sulfuric acid, or sodium chloride to get NaCl. It handles ionic compounds with Stock notation (iron(III) oxide), common acids, polyatomic ions, hydrates, and simple organic compound names for alkanes, backed by a built-in library of frequent compounds. Use it as a formula-to-name converter for homework, or a name-to-formula tool when you only know the compound's name. Free, instant, and browser-based.
如何使用 Chemical Name Generator
- Choose Formula → Name or Name → Formula.
- Enter a formula (H2SO4, Ca(OH)2, CuSO4·5H2O) or a name (nitric acid, ammonium chloride).
- For variable metals in names, use Roman numerals in parentheses: iron(III) oxide.
- Read the converted formula or name plus the naming type used.
- Copy the result for homework or lab notes.

常見問題
- What naming system does this use?
- It follows common general-chemistry nomenclature: Stock notation for transition metals, -ide endings for monoatomic anions, -ate/-ite for oxoanions, and standard acid names (e.g. sulfuric acid for H2SO4).
- Can it name organic molecules?
- It covers simple alkanes (methane through decane) and common small organics in the lookup table. Complex IUPAC organic names are not supported.
- How do I enter hydrates?
- Use a middle dot: CuSO4·5H2O for formula mode, or names like copper(II) sulfate pentahydrate for name mode.
- Why does iron need (II) or (III) in the name?
- Transition metals with variable oxidation states use Roman numerals in Stock notation to show the charge. Fe2O3 is iron(III) oxide because iron is +3.
- Can it generate IUPAC names for organic compounds?
- It generates IUPAC-style names for simple alkanes (methane through decane) and names common inorganic and small organic compounds from its library. Full systematic IUPAC naming of complex branched or functional-group organics is not supported.
- What if my compound is not recognized?
- Try the lookup-friendly common name, simplify the formula, or use related tools like the molar mass or oxidation number calculators for further analysis.
