Detailed explanation-1: -A bond in which the electronegativity difference between the atoms is between 0.5 and 2.0 is called a polar covalent bond. A polar covalent bond is a covalent bond in which the atoms have an unequal attraction for electrons and so the sharing is unequal.
Detailed explanation-2: -A bond in which electrons are shared unevenly is known as a polar bond. Much like the poles on a mini magnet, the atoms connected by a polar bond become positive and negative poles.
Detailed explanation-3: -Atoms of different electronegativities attract electrons unequally. This causes the unequal sharing of electrons, which causes polarity in bonds.
Detailed explanation-4: -A polar bond is a type of covalent bond. A bond between two or more atoms is polar if the atoms have significantly different electronegativities (>0.4). Polar bonds do not share electrons equally, meaning the negative charge from the electrons is not evenly distributed in the molecule.
