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

- 3-78 Nitrous oxide, N20, laughing gas, is a colorless, nontoxic, tasteless, and odorless gas. It is used as an inhalation anesthetic in dental and other surgeries. Because nitrous oxide is soluble in vegetable oils (fats), it is used commercially as a propellant in whipped toppings Nitrous oxide dissolves in fats. The gas is added under pressure to cans of whipped topping. When the valve is opened, the gas expands, thus expanding (whipping) the topping and forcing it out of the can.
