Detailed explanation-1: -A Polar Covalent Bond is created when the shared electrons between atoms are not equally shared. This occurs when one atom has a higher electronegativity than the atom it is sharing with.

Detailed explanation-2: -Because they have the same electronegativity, they will share their valence electrons equally with each other. This type of a covalent bond where electrons are shared equally between two atoms is called a non-polar covalent bond.

Detailed explanation-3: -Electron ‘sharing’ occurs when the electrons in the outermost electron shell, or valence shell electrons, from one atom can be used to complete the outermost electron shell of another atom without being permanently transferred, as occurs in the formation of an ion.

Detailed explanation-4: -A nonpolar covalent bond is one in which the electrons are shared equally or nearly equally between two atoms.

Detailed explanation-5: -Polar molecules are those that possess regions of positive and negative charge. Water is an example of a polar material. The type of bonds it has, when coupled with its shape, gives one end of the molecule a slight positive charge (the hydrogen end) and the other a slight negative charge (the oxygen end).
