Chemical language includes the naming of chemicals both systematic and common names, and the names and definitions of significant chemical and physical properties. The relationship of chemical names to chemical structures and formula is also important. And just as with any language if one is to talk chemistry, it helps to be able to pronounce the names and other terms.
Many of the terms and names needed to understand chemical "language" are introduced. A major part in the language of chemistry is in learning the names of the chemicals (nomenclature).
IUPAC nomenclature practice helps to assign the name of each compound that not only identifies the name but also enables one to draw its structural formula. Some of the IUPAC nomenclature examples are given below.
|S.No ||Molecular formula
||Condensed structural formula
IUPAC nomenclature practice problems are given below.
- The IUPAC prefix for the given compound is pent-
- The molecular formula for the given compound is found to be C5H12.
- The IUPAC name of this compound is pentane.
The given compound is CH3-CH(CH3)-CH2-CH3.
The parent chain is butane.
In the 2nd carbon one methyl group is attached.
So the IUPAC name for this compound will be 2-methyl butane.

IUPAC Organic NomenclatureBack to Top
- The first field includes the names and position of substituents.
- The second field contains the compound root word.
- The third field is what we call the multiple bond index.
- The fourth field defines the principle functional group.
Before the IUPAC rules were accepted, trival or common names were widely employed, and many of these were incorporated into IUPAC system.

How to name chemical compounds?
A chemical name is a one to two letter designation for an element derived from the elements name. Chemical symbols can be written more quickly than the names and they occupy less space. The following table describes the naming of chemical compounds.
|1||Binary compounds||Type 1: Ionic (containing a metal element with only one change possibility and a nonmetal element)||
|Type 2: Ionic (containing a metal element that has more that one charge possibility and a nonmetal element)|
|Type 3: Covalent (containing two nonmetal elements)||
|2||Other than binary compounds||Ionic compound containing at least three elements.||Name the parts of the compound in the order presented in the formula.|
Common Chemical NamesBack to Top
Chemical nomenclature is the system of names that chemists use to identify compounds. Chemical names of common substances have distinct limitations. When a new substance is formulated it must be named in order to distinguish it from all other substances is shown below.
Chemical Group NamesBack to Top
Group number in the periodic table equals the number of electrons in the outer shell. Therefore all the atoms of elements in the same group have the same number of electrons in their outer shells.
