Description: The molecular orbital theory revolutionised the study of chemical bonding by approximating the states of bonded electrons. Let's learn more about this theory.

Question

Match the items given in Column I with examples given in Column II.

	Column I		Column II
(i)	Hydrogen bond	(a)	$C$
(ii)	Resonance	(b)	$LiF$
(iii)	Ionic solid	(c)	$H_{2}$
(iv)	Covalent solid	(d)	$HF$
		(e)	$O_{3}$

Accepted Answer

(i)Hydrogen bond-----(d) $HF$

Hydrogen bond can be defined as the attractive force which binds hydrogen atom of one molecule with the electronegative atom $(F, O or N)$ of another molecule.

(ii)Resonance-----(e) $O_{3}$

According to the concept of resonance, whenever a single Lewis structure cannot describe a molecule accurately, a number of structures with similar energy, positions of nuclei, bonding and non-bonding pairs of electrons are taken as the canonical structures of the hybrid which describes the molecule accurately.

(iii)Ionic solid-----(b) $LiF$

Ionic solids are solids held together by ionic bonds. They are lattices composed of oppositely charged ions. Ionic solids tend to have high melting points.

(iv)Covalent solid-----(a) $C$

A network solid or covalent network solid is a chemical compound in which the atoms are bonded by covalent bonds in a continuous network extending throughout the material. Example: Diamond.

(i) → (d) (ii) → (e) (iii) → (b) (iv) → (a)
