Interpretation Introduction

Interpretation:

The given compound KClO has to be named.

Concept Introduction:

Generally the ionic compound consists of cation and anion.

Cation: When electrons are removed from the atom that results to form positively charged ion called cation.

Anion: Addition of electron to atom results to form negatively charged ion called anion.

The nomenclature of inorganic compounds involves following rules:

  • Generally many ionic compounds are binary in which the metal cations are named first which then followed by naming nonmetallic anion.
  • In ionic compound the metal cations generally hold their metal name itself and the metal anions hold their respective metal name with suffix "-ide" with it.
  • The prefixes on each atom indicate the number of those atoms in the compound.
  • The number written on the subscript of the anion is numerically equal to the charge on the cation and vice versa.
  • Subscripts are discarded when the numerical charge on cation and anion are equal.
  • When a metal has more than one positive oxidation state, its lowest oxidation number has name of the metal ion ending with ‘ous’ and highest oxidation number has name of the metal ion ending with ‘ic’. This rule is applicable when oxidation number of metal is not more than three.
  • If a metal ion has multiple numbers of oxidation states more than three, then Roman numeral has to be used within square brackets to indicate the oxidation number of metal ion.
  • Nomenclature of binary acids and oxoacids are not similar. Binary acids are named based on the non-metal atom present in them. Oxoacids are named on the basis of polyatomic anion present in them.
  • Naming binary molecular compounds is also similar to binary ionic compounds.
  • The first element is named as such while second element is added with prefix which describes the number of respective atoms present.
