Chemistry Nomenclature
Here are the principal naming conventions for ionic compounds along with examples to show how they are used.
Chemistry nomenclature. Each chemical name should refer to a single substance. Nomenclature a collection of rules for naming things is important in science and in many other situations this module describes an approach that is used to name simple ionic and molecular compounds such as nacl caco 3 and n 2 o 4 the simplest of these are binary compounds those containing only two elements but we will also consider how to name ionic compounds containing polyatomic ions. Ionic compound nomenclature or naming is based on the names of the component ions. Long before chemists knew the formulas for chemical compounds they developed a system of nomenclature that gave each compound a unique name.
A chemical nomenclature is a set of rules to generate systematic names for chemical compounds the nomenclature used most frequently worldwide is the one created and developed by the international union of pure and applied chemistry iupac. When naming compounds you need to understand these different rules as well as how to spot clues that will help you properly name the compounds. For example water is not. Ideally every possible organic compound should have a name from which an unambiguous structural formula.
A majority of these compounds however are referred to by singular names that are unique. 4 steps to naming compounds in chemistry nomenclature is published by ernest wolfe in countdown education. In chemical nomenclature the iupac nomenclature of organic chemistry is a method of naming organic chemical compounds as recommended by the international union of pure and applied chemistry iupac. The nomenclature of substituted benzene ring compounds is less systematic than that of the alkanes alkenes and alkynes.
Today we often use chemical formulas such as nacl c 12 h 22 o 11 and co nh 3 6 clo 4 3 to describe chemical compounds but we still need unique names that unambiguously identify each compound. Today scientists often refer to chemicals by their common names. Ever feel like there s a international team of bad guys changing all of the easily remembered chemical names and turning them into test failing number infus. The iupac s rules for naming organic and inorganic compounds are contained in two publications known as the blue book and the red book respectively.
In all cases ionic compound naming gives the positively charged cation first followed by the negatively charged anion. Naming basic chemical compounds is essential if you want to succeed in chemistry since the name of the compound clearly defines what it is. A few mono substituted compounds are named by using a group name as a prefix to benzene as shown by the combined names listed below. Ionic compounds consist of cations positive ions and anions negative ions.
