Electrovalent Compound
The compounds which
contain ionic or electrovalent bonds are known as Electrovalent or Ionic
Compounds. Mainly electrovalent compounds are formed due to reaction between
highly electropositive and highly electronegative atoms.
Characteristics of Electrovalent Compounds
1. Crystal Structure:
In solid state of electrovalent compounds anions
and cations are arranged in regular manner called as crystal, In which anions
surrounded by definite number of cations and cations surrounded by definite
number of anions.
2. Physical Nature:
Ionic or electrovalent
compounds are generally hard and their hardness increases with increasing ionic
charge and decreasing distance between ions.
3. Solubility:
Positive ion of ionic compound attach
with negative part of polar solvent and negative ion of ionic compound attach
with positive part of polar solvent, so ionic or electrovalent compounds are
soluble in polar solvents like water and insoluble in non polar solvents like
benzene, ether, alcohol.
4. Melting Point and Boiling Point:
Electrovalent or ionic compounds have high
Melting and boiling points because they need large amount of energy to break
strong ionic bonds.
5. Electrical Conductivity:
In molten and solution forms electrovalent compounds conduct electricity because ions flows in molten and solution forms.+1 like and share if you like our work to motivate us.
