Answer
Pure Covalent Bond: It is formed between the elements having same electronegativity values. It is called pure covalent as it has about zero electronegativity difference between the elements. It is non-polar in nature.
Polar Covalent Bond: In this bond, there is a distinct difference between the electronegativities of the elements so that the charge is distributed between partial positive and partial negative, due to which bond becomes polar
Ionic Bond: Ionic bond is formed by the complete transfer of electron (s) between the elements. Electronegativiity difference between the bonding elements is large.
