Binary Compounds

Binary Compounds

Chemical compound that contains exactly two different elements

Binary Ionic Compounds

-Compounds in which two types of ions (metal cation and nonmetallic anion) combine to form a ionic compound

-Examples are Calcium chloride (CaCl₂), sodium fluoride (NaF), and magnesium oxide (MgO),

Two types of Binary Ionic Compounds

Type 1: The binary ionic compound in which cation can has only one form (charge), like Na⁺, Mg⁺² and Al⁺³.
Few examples of type 1 binary ionic compounds are as, NaCl, KBr, LiF, CaI₂, AlF₃, MgBr₂ etc.
Type 2: The binary ionic compound in which cation can have the multiple forms (charge), like Fe⁺² and Fe⁺³
Examples of type 1 binary ionic compounds are as FeCl₂ and FeCl₃, AgCl and AgCl_2.

How to name Binary Ionic Compounds

1. Metal (Cation) + NonMetal (anion) –ide

Example:

NaCl

Na – Sodium

Cl – Chlorine

Sodium + Chlorine –idea = Sodium Chloride

2. Use of –ous and –ic

-ous = lower one

-ic = higher one

Example:

FeCl₂ and FeCl₃

FeCl₂ = Ferrous Chloride or Iron (II) Chloride

FeCl₃ = Ferric Chloride or Iron (III) Chloride

Binary Covalent Compounds

-Made from two nonmetal elements. In binary covalent compound sharing of electrons takes place.
-Examples of binary covalent compounds are:  N₂O, P₂O₅, N₂H₄, CH₄ and H₂O.

How to name Binary Covalent Compounds

1.Prefix + Nonmetal  +  Prefix +nonmetal-ide

List of Prefix:

Example:

N₂H₄

Di- nitrogen  +   Tetra- hydrogen –ide

= Dinitrogen Tetrahydride

2.      Use of –ous and –ic

-ous = higher

-ic = lower
