===Covalent bond===

{{මූලික|Covalent bond}}

 

A [[polar covalent bond]] is a covalent bond with a significant ionic character. This means that the electrons are closer to one of the atoms than the other, creating an imbalance of charge. They occur as a bond between two atoms with moderately different electronegativities, and give rise to [[dipole-dipole interactions]]. The electronegativity of these bonds is 0.3 to 1.7 .
