(a)
Interpretation:
The given bond is to be classified as ionic, covalent or polar covalent bond.
Concept introduction:
Ionic bonds are formed when there is complete transfer of electrons from one atom to another forming the bonds.
Covalent bond is formed by sharing of electrons between the atoms forming the bonds
Polar covalent bond is formed between two different atoms.
Non-polar covalent bond is between two same atoms.
A bond is polar if there is difference in electronegativity values of atoms forming the bond.
Electronegativity is denoted by

Answer to Problem 9A
Covalent bond
Explanation of Solution
Thus,
The bond is formed between same atoms. Electronegativity difference is zero. So it is covalent compound.
