Concept explainers
Interpretation:
The polar covalent bond is to be differentiated from covalent bond.
Concept introduction:
Covalent bond is formed by sharing of electrons between the atoms forming the bonds.
It is of two types:
Polar covalent bond
Non-polar covalent bond

Answer to Problem 3RQ
Polar covalent bond is formed between two different atoms.
Non-polar covalent bond is between two same atoms.
Explanation of Solution
The bond formed in
The bond formed is polar when there is electronegativity difference between the atoms forming the bond due to which atoms gets polarity.
More electronegative atom acquires partially negative charge and less electronegative atom acquires partial positive charge.
Thus polar covalent bond has some ionic character but covalent bond is completely non-polar.
