IUPAC Naming Rules:
1. Identify the longest carbon chain
2. Number the chain to give substituents lowest numbers
3. Name substituents as prefixes
4. Assign stereochemistry if needed

The International Union of Pure and Applied Chemistry (IUPAC) nomenclature provides systematic names for chemical compounds. It allows precise communication about molecular structures without ambiguity.
The calculator identifies key features of the molecular formula:
1. Functional groups and their positions
2. Longest carbon chain
3. Substituents and their locations
4. Stereochemical configuration
Example: CH₃CH₂OH becomes "Ethanol" (common) or "Ethyl alcohol" (IUPAC)
Details: Standardized names prevent confusion in scientific literature, safety documentation, and regulatory compliance. IUPAC names precisely describe molecular structure.
Tips: Enter the molecular formula using standard notation (e.g., CH3COOH). Select whether the compound is organic or inorganic for appropriate naming rules.
Q1: Why are some compounds known by common names?
A: Common names persist for historical reasons, especially for well-known substances like water (H₂O) or acetic acid (CH₃COOH).
Q2: What's the difference between IUPAC and common names?
A: IUPAC names follow strict systematic rules, while common names may reflect origin or properties (e.g., "formic acid" from ants).
Q3: How are complex molecules named?
A: Complex molecules are broken into parent chains and substituents, with numbering indicating positions of functional groups.
Q4: Are there different rules for inorganic compounds?
A: Yes, inorganic naming follows different conventions based on oxidation states and composition rather than carbon chains.
Q5: Can this calculator name all chemical compounds?
A: This simplified version handles common compounds. For complex molecules, specialized chemical naming software is needed.
