Chemical Name Calculator

A Chemical Name Calculator is a tool that helps convert between chemical formulas and their corresponding names.

You input the chemical formula H2SO4, chemical name calculator would output "sulfuric acid." And when you input "sodium chloride," it would return the chemical formula NaCl.

Chemical Name Formula

There are systematic rules governed by IUPAC (International Union of Pure and Applied Chemistry) nomenclature. These rules consider factors such as:

The type of compound (ionic, covalent, acid, etc.)

The elements present and their oxidation states

The structure of the molecule

Let’s take an example of naming an ionic compound:

Formula: CaCl2

Identify the cation (positive ion): Ca2+ (Calcium)

Identify the anion (negative ion): Cl- (Chloride)

Combine the names: Calcium Chloride

The resulting name is "Calcium Chloride."

How to Calculate Chemical Name and Formula

Let’s walk through an example:

We want to determine the name and formula for a compound composed of aluminum and oxygen.

1. Identify the elements: Aluminum (Al) and Oxygen (O)
2. Determine their typical oxidation states: Al3+ and O2-
3. Balance the charges: We need 2 Al3+ ions for every 3 O2- ions to balance the charges.
4. Write the formula: Al2O3
5. Name the compound:
   • Cation first: Aluminum
   • Anion second: Oxide (for simple oxygen anion)

The final name is "Aluminum Oxide" and the formula is Al2O3.

For more complex organic compounds:

Identify the longest carbon chain

Note any functional groups and their positions

Apply IUPAC naming rules

For instance, CH3CH2CH2OH:

Longest chain: 3 carbons (propan-)

Functional group: -OH (alcohol, becomes -ol)

Position: On the last carbon (no number needed)

The name is therefore “propanol” (or 1-propanol to be more specific).
