What is electronegativity ?
The tendency of an electron to attract
bond pair electron towards itself is known as electronegativity. This tendency generates
a polarity in molecule causes polar molecule. Example: H2O, HCl, KCl
Electronegativity trend:
F>Cl >Br>I
It is measured
by Pauling scale.
What happen
if two atoms of equal electronegativity bonded:
If two atoms
of equal electronegativity bonded with each other then covalent bond is formed
between these two atoms. Because equal electron are shared by two atoms.
