(a)
Interpretation:
To analyse the more electronegative element between H and Cl.
Concept Introduction:
Electronegativity is defined as the tendency to attract shared pair of electrons in a molecule.
A covalent bond involves sharing of two electrons between two atoms. When the atoms are of same element the bonding pair is equally shared by two atoms e.g.
But when two bonded atoms are from different elements then, the bonding pair is not equally shared.e.g

Interpretation:
To analyse the more electronegative element between n and O.
