Chemical Name Calculator
Use our naming compounds calculator to find the correct nomenclature by entering chemical formula i.e. CO2 (Carbon Dioxide), NaCl (Salt) and Molecular Weight.
This chemical formula name calculator analyzes the arrangement of atoms, bonds, and functional groups to generate standardized chemical names following IUPAC (International Union of Pure and Applied Chemistry) conventions.
When presented with the molecular structure CH3CH2OH, the calculator identifies the primary functional group (-OH), the carbon chain length (2 carbons), and generates the systematic name “ethanol.”
Chemical Name Calculation Formula
For CH3CH(CH3)CH2COOH the formula is:
- Parent chain: 4 carbons with -COOH (butanoic)
- Substituent: CH3 at position 2 (2-methyl)
- Final name: 2-methylbutanoic acid
Let’s perform some complex chemical name calculations:
CH3CH2CH(OH)CH3:
- Longest chain: 4 carbons (butane)
- Functional group: -OH at position 2
- Systematic name: 2-butanol
CH3CH2CH=CHCH2CH3:
- Six-carbon chain with double bond
- Double bond starts at carbon 3
- Systematic name: 3-hexene
(CH3)2CHCH2COOH:
- Parent chain: 4 carbons with -COOH
- Two methyl groups at position 3
- Systematic name: 3,3-dimethylbutanoic acid
How to Find Names of Ionic Compounds
Consider Fe2O3:
- Iron (Fe) has a +3 charge
- Oxygen (O) has a -2 charge
- Balanced formula requires two Fe3+ and three O2-
- Systematic name: Iron(III) oxide
Naming ionic compounds requires understanding the charge balance between cations and anions. The process involves identifying the metal (cation) and non-metal (anion), determining oxidation states, using Roman numerals for transition metals with multiple oxidation states, and writing the cation first, followed by the anion.
What is Chemical Name?
A chemical name represents a systematic identification system that uniquely describes the composition and structure of chemical substances. It serves as a universal language in chemistry, enabling precise communication about molecular structures across the scientific community.
